Summary: [kn_IN] Lohit Kannada glyphs of consonants with vowel
signs -II, -EE, -OO and -AI should be optimized
Regression: ---
Story Points: ---
Classification: Fedora
OS: Unspecified
Reporter: samjnaa(a)gmail.com
Type: Bug
Documentation: ---

Mount Type: ---
Status: NEW
Component: lohit-kannada-fonts
Product: Fedora
Description of problem:
Currently the Lohit Kannada fonts unnecessarily contain separate glyphs for
consonants with vowel signs -II, -EE, -OO and -AI. These are merely sequences
of other glyphs.
In the case of -II, -EE, -OO the glyphs are the same as those of the
corresponding short vowels plus a separate glyph 0CD5 Kannada Length Mark ೕ
(unlike in Telugu where the length mark ligates with the syllable). Therefore
instead of doing substitutions of:
CONSONANT + VOWEL_SIGN_II/EE/OO --> CONSONANT_VOWELSIGN_II/EE/OO
the optimized way would be to do:
CONSONANT + VOWEL_SIGN_II/EE/OO --> CONSONANT_VOWELSIGN_I/E/O LENGTH_MARK
If this is done, any changes that are reflected on the
CONSONANT_VOWELSIGN_I/E/O glyphs would automatically reflect for the long
vowels as well without additional work being needed. For instance, see my
recent report of bug 825104. If that bug is fixed for short vowels I, E and O,
automatically it would reflect for II, EE and OO also.
As for -AI, it is merely sequence of glyph for -E plus 0CD6 Kannada AI Length
Mark ೖ. So instead of doing substitutions of:
CONSONANT + VOWEL_SIGN_AI --> CONSONANT_VOWELSIGN_AI
the optimized way would be to do:
CONSONANT + VOWEL_SIGN_AI --> CONSONANT_VOWELSIGN_E AI_LENGTH_MARK
with same benefits as above.
Further, when handling combinations of:
CONSONANT1 + VIRAMA + CONSONANT2 + VOWEL_SIGN_II/EE/OO/AU
by separating the length mark as recommended here, the sub-base form of
CONSONANT2 can be placed closer to the base CONSONANT1 which is also
typographically a desirable factor in a good font. The rules would be:
CONSONANT1 + VIRAMA + CONSONANT2 + VOWEL_SIGN_II/EE/OO/AU -->
CONSONANT1_VOWEL_SIGN_I/E/O + SUB_BASE_CONSONANT_2 + (AI_)LENGTH_MARK
Version-Release number of selected component (if applicable):
2.5.1
How reproducible:
Examine the internals of Lohit Kannada font.
Actual results:
Currently there are separate glyphs for consonants with vowel signs -II, -EE,
-OO and -AI unnecessarily. These are merely sequences of other glyphs.
Therefore any change effected on the component glyphs has to be re-done here.
Expected results:
The superfluous glyphs should be removed and the appropriate effect should be
achieved by appropriate smartfont rules as indicated above.
Additional info:
This would also reduce the size of the font. Not an issue on laptops/desktops
but nowadays Lohit fonts are finding their way into smaller screens such as
smartphones, and it would be good to have a trim font with small footprint.

[Bug 1332250] New: Incorrect font configuration
by Red Hat Bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1332250
Bug ID: 1332250
Summary: Incorrect font configuration
Product: Fedora
Version: rawhide
Component: open-sans-fonts
Assignee: pvoborni(a)redhat.com
Reporter: dag.odenhall(a)gmail.com
QA Contact: extras-qa(a)fedoraproject.org
CC: fonts-bugs(a)lists.fedoraproject.org,

When a website requests Open Sans, Firefox uses Comfortaa. I have both fonts
installed. I don't know if the following is the cause, because the matching
works correctly with fc-match, but I discovered this and it's still wrong, I
think.
The open-sans-fonts package includes this fontconfig rule:
<alias>
<family>Open Sans</family>
<prefer>
<family>sans-serif</family>
</prefer>
</alias>
In my understanding of fontconfig, this is saying "Edit the font family list
for Open Sans and prepend the sans-serif font family" i.e. Open Sans itself is
given *less* priority than all other sans-serif fonts. The
aajohan-comfortaa-fonts package includes this (correct) rule:
<alias>
<family>sans-serif</family>
<prefer>
<family>Comfortaa</family>
</prefer>
</alias>
And so perhaps C being early in the alphabet or perhaps because being the next
fontconfig file in my conf.d (I don't fully understand fontconfig) the combined
effect ends up being "When looking for Open Sans, the first match is sans-serif
which in turn is Comfortaa".
I think the Open Sans rule above should be edited to something closer to the
Comfortaa rule above, like:
<alias>
<family>sans-serif</family>
<prefer>
<family>Open Sans</family>
</prefer>
</alias>
The second rule it contains is also wrong, I think, and not like how any other
fonts are configured:
<alias>
<family>sans-serif</family>
<default>
<family>Open Sans</family>
</default>
</alias>
Should probably also swap the families like so:
<alias>
<family>Open Sans</family>
<default>
<family>sans-serif</family>
</default>
</alias>
This Firefox bug seems relevant but I think this is a bug in the packaged font
configuration and really unrelated to Firefox (I didn't read the whole bug):

[Bug 1321551] New: RFE: Recommend some specific general purpose font
by Red Hat Bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1321551
Bug ID: 1321551
Summary: RFE: Recommend some specific general purpose font
Product: Fedora
Version: rawhide
Component: fontconfig
Assignee: tagoh(a)redhat.com
Reporter: ville.skytta(a)iki.fi
QA Contact: extras-qa(a)fedoraproject.org

Currently fontconfig has a dependency on font(:lang=en). For minimal setups
where fontconfig is involved in that don't specify anything more specific than
that, it results in getting the first satisfying package by alphabetical sort
order to be installed. At the moment that is aajohan-comfortaa-fonts, which is
not a very good default, and could change based on what names of packages are
available.
Instead, I suggest adding (in addition to the existing hard dependency on
font(:lang=en)) a Recommends that would by default (with dnf) pull in something
that is a better default and already a default in common Fedora installations,
such as abattis-cantarell-fonts which AFAIK is the default for GNOME. Some
other potential candidates would be liberation-sans-fonts and
dejavu-sans-fonts. Not sure if Suggests would work for this purpose, or if it
needs to be Recommends.

The parse_charstrings function in type1/t1load.c in FreeType 2 does not ensure
that a font contains a glyph name, which allows remote attackers to cause a
denial of service (heap-based buffer over-read) or possibly have unspecified
other impact via a crafted file.
