TTF of replacement glyphs and attestations for the same
Description of problem:
The Tamil digits in the Lohit Tamil font are not true to the actual printed
glyphs and hence do not look so good even though the rest of the Lohit Tamil
font is OTOH exceptionally of good quality.
The glyph of one Tamil symbol 0BF6 TAMIL DEBIT SIGN is also not true to the
printed glyphs.
Version-Release number of selected component (if applicable):
2.5.0
How reproducible:
Using Lohit Tamil font, compare glyphs to existing printed glyphs.
Actual results:
The relative proportions, shapes and lengths of the strokes in some of the
glyphs are not according to the actual usage in printing. Some changes were
subtle, some were very obvious.
Expected results:
For maintaining high quality, the above problem should be fixed.
Additional info:
I have attached a small font with the replacement glyphs. Mostly they are:
1) glyphs copied from elsewhere in the font or another Lohit font (for zero)
2) existing glyphs with positioning of some nodes slightly modified
If above not possible, only then I have changed the number of nodes.
I have also provided the attestations from printed books. Especially please
note that the Tamil zero should be perfectly circular, and the 0BF6 TAMIL DEBIT
SIGN should be derived from Tamil PA ப. [In the Unicode chart, the glyph of
0BF6 is wrong and I have asked them to correct it.]
Please make sure to autohint the glyphs as due to change in number of points
the original hinting information might have been lost. Sorry for that.

Created attachment 572489
--> https://bugzilla.redhat.com/attachment.cgi?id=572489
Contains JPEG of attestation from printed book, PDF of current and desired
appearance and TTF of replacement glyphs
Description of problem:
The SHI SHII glyphs in Lohit Tamil font need to be corrected. In both cases the
vowel sign is not correctly positioned over the consonant. Further in SHI the
vowel sign does not attach to the consonant at all.
Version-Release number of selected component (if applicable):
2.5.0
How reproducible:
Use Lohit Tamil font.
Steps to Reproduce:
1. Type ஶி ஶீ by selecting Lohit Tamil font.
2. Zoom to large size.
3. Especially note the minute gap between SHA and VS-II.
Actual results:
You can see that the described problem exists.
Expected results:
The vowel sign should be correctly positioned w.r.t. the consonant and it
should correctly attach to the consonant.
Additional info:
Currently within the SHI SHII glyph of the Lohit Tamil font the contours for
the vowel sign are separate and not unified with the consonant's contours. This
causes overlapping nodes which is not recommended.
Furthermore the RSB of SHI is zero, which is inappropriate. Compare the RSB
values of glyphs of other consonants + VS-I.
I have modified the glyphs by taking the position of the vowel signs and the
RSB values of PI/PII (PA + VS-I and VS-II) as a model since the right-side
contour shape of PA is closest to that of SHA. I have provided glyphs with
unified and non-unified contours. Please find it in the attachment.
I recommend to use the unified contours and have only given the non-unified
contours in case you wish to do any other adjustment of positioning (unlikely).
I have also provided attestation for the actual appearance of SHI/SHII as seen
in printed books,

+++ This bug was initially created as a clone of Bug #659214 +++
Hi guys,
bug #659214 adds support for some Cyrillic characters to the Liberations fonts
family.
M. Balabanov, a member of a localization mailing list reported a problem with
the glyphs.
The glyphs for CYRILLIC CAPITAL LETTER I WITH GRAVE (U+040D) is wrong (except
for Mono Regular). Instead of Ѝ it is Ǹ (i.e it's swapped).
The actual glyph is LATIN CAPITAL LETTER N WITH GRAVE (I just made that up,
hopefully you get the point).
This is with version:
1.07.1 of the fonts.

Hi,
as the subject line suggests, the patch applied in
liberation-fonts-1.07.2-4.fc* to fix #799384 (Problems with glyphs Ѝ (U+040D)
for Bulgarian language) reverts the patches applied in previous revisions which
were applied to fix #714191 (Glyph '1' not the same width as other numerals)
and #715309 (fixed hinting problem of Liberation Sans Bold character "u" at
particular point size). It thus re-opens these bugs.

Story Points: ---
Type: ---
Some PDF files that include symbols from the ZapfDingbats font without
embedding it (like [1]) render incorrectly on Fedora 15 when reading them in
Evince, Okular or GIMP. According to Poppler developers[2], this is because
Fedora doesn't include a substitution rule for this font, which can be found at
[3].
I could test that adding this rule fixes the problem. So I think tit should be
added, together with the Symbol -> Standard Symbols L one.
For reference, the file shipping the Dingbats font seems to be
/usr/share/fonts/default/Type1/d050000l.pfb.

Classification: Fedora
Description of problem:
After updating to the latest FreeType build for which the bytecode interpreter
has been enabled, fonts are rendered with uneven quality. The system font used
e.g. for button labels is very thin now and certain popular web fonts (e.g.
Verdana) are rendered surprisingly poorly.
Look at the four attached screenshots which demonstrate the various
combinations for which the bytecode interpreter is enabled (disabled) and
webcore fonts are installed (removed).
Version-Release number of selected component (if applicable):
freetype-2.4.4-3.fc15
How reproducible:
Always.
Steps to Reproduce:
1. Launch firefox.
2. Open http://www.bbc.co.uk .
Actual results:
Partially poor rendering depending on whether the bytecode interpreter is
enabled or not.
Expected results:
Acceptable rendering quality throughout all font families.
Additional info:
Reverting to freetype-2.4.4-2.fc15 restores globally good font rendering.
