[Bug 825081] New: Lohit Kannada font does not properly handle vowel signs in consonant clusters
by Red Hat Bugzilla 12 Dec '17

https://bugzilla.redhat.com/show_bug.cgi?id=825081 Bug ID: 825081 QA Contact: extras-qa(a)fedoraproject.org Severity: unspecified Version: 16 Priority: unspecified CC: fonts-bugs(a)lists.fedoraproject.org, i18n-bugs(a)lists.fedoraproject.org, psatpute(a)redhat.com Assignee: psatpute(a)redhat.com Summary: Lohit Kannada font does not properly handle vowel signs in consonant clusters Regression: --- Story Points: --- Classification: Fedora OS: Unspecified Reporter: samjnaa(a)gmail.com Type: Bug Documentation: --- Hardware: Unspecified Mount Type: --- Status: NEW Component: lohit-kannada-fonts Product: Fedora Created attachment 586752 --> https://bugzilla.redhat.com/attachment.cgi?id=586752&action=edit ODT and PDF for test-case Description of problem: This seems to be a resurfacing of bug #223971 but since I saw no way to reopen that bug (sorry if I'm wrong) I'm reporting this again. Version-Release number of selected component (if applicable): 2.5.1 How reproducible: In a word processor, select Lohit Kannada font and input Kannada Unicode sequences having consonant clusters of the format CCV. I have attached a sample ODT. Actual results: Except in a few cases of "popular" consonant clusters like K.SSA ಕ್ಷ and J.NYA ಜ್ಞ, the vowel signs are not attached properly. When the same text is rendered with other fonts (like Tunga of Microsoft even loaded into Linux's LibreOffice) the sequences are shown properly without overlaps or malformed glyphs. Expected results: The Kannada language uses lots of Sanskrit-based words and hence has many consonant clusters with two and even three consonants. Also, when English words are transliterated in Kannada script like ಎಕ್ಸ್ಪ್ಲೋರ್ (explore) etc for sign-boards etc, even more consonant clusters will occur. In all these cases Lohit Kannada should be able to gracefully handle such consonant clusters and not output overlapping or malformed glyphs. Additional info: I have attached an ODT and PDF file demonstrating the problem. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 827516] New: [kn_IN] Vowel Signs U and UU do not correctly attach to many consonants in Lohit Kannada

While in most cases, by virtue of appropriate RSB and LSB values of the consonant glyph and vowel sign glyph, the simple sequence of the two glyphs creates an appropriate appearance, this leaves out several instances where the glyphs do not overlap at all and hence appear disjointed. For a professional appearance of the font, this should be fixed. Version-Release number of selected component (if applicable): 2.5.1 How reproducible: Input all possible sequences of Kannada consonants with vowel signs U and UU. (See attached ODT for text. Use BabelMap [http://www.babelstone.co.uk/software/babelmap.html] if you want the codepoints.) Actual results: You can see (as in the attached PDF) that some consonants do not properly get attached to the vowel signs U and UU. Expected results: All consonants should properly get attached to the vowel signs U and UU. Additional info: Consonants which are not properly joined with vowel sign U: KA* NYA DDA DA BA RA SSA** RRA LLLA*** * = see at high magnification ** = may need separate precomposed glyph with some adjustment to shape of left side of vowel sign *** = so-called FA of Kannada Unicode Consonants which are not properly joined with vowel sign UU: Those already listed above for U, plus GHA and LLA, due to the shorter height of the left-side ending node of this vowel sign. I think in most cases appropriate kerning should solve the problem, except for SSA + -U/-UU, GHA + -UU and LLA + -UU where separate glyphs would be advisable. It is curious to note that DDA DA and BA are all disjointed whereas their aspirated counterparts DDHA DHA and BHA which all have only an additional notch-like stroke at the bottom are correctly joined with the vowel sign. I think the LSB RSB values are carelessly allotted in some cases, unfortunately. Other problems: CU JU -- the pointed part on the left of the vowel sign U passes through the consonants and comes out above (see carefully) -- actually *negative* kerning is needed here so that the pointed part should only enter the consonant and not again exit it. (It seems this problem does not occur for vowel sign UU due to the shorter height of the left-side ending node of this vowel sign which causes a problem with GHA and LLA instead -- see above!) Note: Unfortunately I will not be able to provide a TTF patch for this as I am already short of time on my official projects. Please take care of it.

[Bug 839303] New: [ta_IN] Submission of glyphs for Tamil fractions/symbols to be included in the Lohit Tamil fonts

Seven of these are being proposed for the Tamil BMP block and rest for a new Tamil Supplement block in the SMP. For the glyphs required for the code chart I have largely devised new glyphs based on existing Lohit Tamil glyphs under the derivative rights granted by the OFL. Some glyphs which could not be derived, I created myself using Inkscape and other tools. I would like to donate all these glyphs to the Lohit project under the OFL for eventual inclusion into the Lohit Tamil/Tamil Classical fonts. For now they may be included in the PUA of an unofficial fork of the Lohit Tamil fonts. When they are eventually encoded in Unicode, they may be officially mapped to the new codepoints and included in the official distribution of the Lohit Tamil/Tamil Classical fonts. Using Lohit Tamil glyphs for Unicode code chart: ------------------------------------------------ In the proposal, I am also requesting the Unicode / ISO 10646 project editors to use the Lohit Tamil font for the Unicode Tamil code charts (Tamil block, and newly proposed Tamil Supplement block) because: 1) When the new characters are encoded and my glyphs used for the code chart, it would look good to maintain stylistic uniformity in the code chart, and my designed glyphs are stylistically like the Lohit Tamil glyphs as they are mostly derived from them. So it would be good to use Lohit Tamil glyphs throughout. 2) There are currently 72 Tamil characters in Unicode 6.1.0. The present proposal almost doubles the number with 62 new characters. It would be a significant and unnecessary effort for anyone else to duplicate my glyph design work for so many characters to keep in with the current Tamil code chart font style. So switching to Lohit Tamil for all glyphs is easier and advisable. 3) Personally I think the glyphs of Lohit Tamil are much "cleaner" than the existing Tamil code chart font, and more representative of the nature and beauty of the Tamil script. 4) The OFL already permits the use of the Lohit Tamil font (and its derivatives) for any purpose, so there are (hopefully) no legal issues pertaining which need to be cleared between Unicode and Red Hat (but of course, IANAL). I also sincerely request the cooperation of the Lohit / Fedora / Red Hat people in permitting the Lohit Tamil glyphs to be used for the Unicode Tamil code charts (i.e. for two blocks). Fonts with new glyphs: ---------------------- I attach herewith a ZIP file containing three font files: 1) Lohit Tamil font, with newly proposed character glyphs mapped to the PUA. 2) Lohit Tamil Classical font, likewise. 3) Lohit Tamil Chart font, containing only glyphs required for the code chart (for existing and new characters, totalling 134 in number, across two blocks Tamil and Tamil Supplement) mapped to the existing and proposed characters for convenience of Unicode / ISO 10646 editors. Behaviour of new characters and requirement from the fonts' side: ----------------------------------------------------------------- None of the newly proposed characters are combining characters in the sense of combining marks. However, most of them are proposed for a new SMP Tamil block and care might need to be taken for proper mapping so that on all platforms the SMP characters are accessible. There is only one sequence of characters which needs to ligate: TAMIL DIGIT ONE ௧ + TAMIL SIGN KALAM (which looks like TAMIL LETTER LLA ள) should always ligate. I have also provided the ligature glyph after the glyphs for the individual characters (mapped to PUA E03F) in the fonts 1 and 2 above. I have not added any substitution mapping however as it is for now only temporarily in the PUA. Etcetera: --------- It is my intention to submit the proposal within a week or so and I will upload/link here a copy of the proposal. If at all any changes are required to the set of glyphs as a result of any feedback from scholars or other sources, I will upload fresh TTF font files. I thank everyone, especially Pravin Satpute, for their support regarding this. -- You are receiving this mail because: You are on the CC list for the bug.

Strictly speaking nakaarapollu means nakaara + pollu=virama so regular form of vowelless-NA న్ is also nakaarapollu but Telugu old grammarian Brown has specifically called a distinct form as nakaarapollu.

A modern-style Telugu font can allow user to select old-style reph by using the sequence RA + VIRAMA + ZWJ + CONSONANT because the plain RA + VIRAMA + CONSONANT would be presented as RA with sub-base form of CONSONANT.

[Bug 1076190] New: Rendering of Unicode tie bars could be improved

https://bugzilla.redhat.com/show_bug.cgi?id=1076190 Bug ID: 1076190 Summary: Rendering of Unicode tie bars could be improved Product: Fedora Version: 20 Component: liberation-fonts Severity: low Assignee: psatpute(a)redhat.com Reporter: rkaldari(a)wikimedia.org QA Contact: extras-qa(a)fedoraproject.org CC: fonts-bugs(a)lists.fedoraproject.org, i18n-bugs(a)lists.fedoraproject.org, petersen(a)redhat.com, psatpute(a)redhat.com Created attachment 874108 --> https://bugzilla.redhat.com/attachment.cgi?id=874108&action=edit comparison between Liberation Sans and Helvetica Description of problem: The rendering of the two Unicode tie bar combining characters (U+035E and U+035F) is not ideal. In particular the characters are quite short and far away from the characters they are tying together. This makes it appear more like a misplaced macron than a tie bar. The rendering in Liberation Sans appears to be equivalent to that of Arial which has the same issues. The rendering in Helvetica is better (see attachment 1). In particular, because the under tie bar (U+035F) is so far away from the other characters, it sometimes gets clipped when rendered, as it appears to fall slightly outside of the bounding box for the line height (see attachment 2). My suggestion would be to make the length of both tie bars slightly longer, and to move both of them slightly closer to the characters they are intended to tie together. Version-Release number of selected component (if applicable): 12-Mar-2014 (2.x) How reproducible: Always Steps to Reproduce: 1. Install latest Liberation Sans (and Helvetica if you want to compare) 2. Go to https://www.mediawiki.org/wiki/User:Kaldari/Font_test_2 Actual results: Tie bars should be slightly longer and closer to the other characters. Expected results: Tie bar are quite short and far away. Additional info: See attachments for more info. -- You are receiving this mail because: You are on the CC list for the bug.

As an example consider the attached testcase which contains left/right/up/down arrows exemplarily. The attached screenshot is a rendering of this file to illustrate the issue: - The arrows are much to small making them hardly discernible, especially at small font sizes. - The horizontally aligned arrows are positioned too low (nearly at the baseline). - Also visible: Hinting for the vertically aligned arrows is bad.
