Summary: [kn_IN] Lohit Kannada glyphs of consonants with vowel
signs -II, -EE, -OO and -AI should be optimized
Regression: ---

Classification: Fedora

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 1607133] New: Wrong rendering of Fira Sans
by bugzilla@redhat.com
https://bugzilla.redhat.com/show_bug.cgi?id=1607133
Bug ID: 1607133
Summary: Wrong rendering of Fira Sans
Product: Fedora
Version: rawhide
Component: mozilla-fira-fonts
Severity: low
Assignee: relrod(a)redhat.com
Reporter: gereon.recht(a)protonmail.com
QA Contact: extras-qa(a)fedoraproject.org
CC: admiller(a)redhat.com,
fonts-bugs(a)lists.fedoraproject.org, relrod(a)redhat.com
Description of problem: Fira Sans looks weird in system applications when set
as default font because different letters are apparently rendered in different
sizes, while other fonts look just fine.
Version-Release number of selected component (if applicable):4.202-3.fc27
How reproducible: Install package mozilla-fira-sans-fonts and set as default
font.
Steps to Reproduce:
1. install mozilla-fira-sans-fonts
2. set Fira Sans as default font
Actual results: Different letters are apparently displayed in different sizes.
Expected results: Correct rendering of the font.
Additional info: Also using freetype-freeworld from rpmfusion for font
rendering, haven't tested yet if that makes a difference. It didn't for any
other font.
