Description Akira TAGOH 2010-03-30 03:51:19 UTC

Description of problem:
All of detailed information is available on my post at the fonts list:
http://lists.fedoraproject.org/pipermail/fonts/2010-March/001117.html

binding="same" in the fontconfig config file prevents to apply the rule for the
specific
language only properly. As a result, fonts is used for non-targetted languages
and it may gives different look and feel in some cases.

I'd propose to get rid of binding="same" from:
 65-madan.conf

Comment 3 Akira TAGOH 2010-04-22 12:12:15 UTC

Testing result:
# rpm -q madan-fonts
madan-fonts-2.000-2.fc13.noarch
# fc-match monospace:lang=en
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
# fc-match monospace:lang=en-us
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
# fc-match monospace:lang=ne
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match monospace:lang=ne-np
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=en
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=en-us
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=ne
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=ne-np
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"

No explicit rules for monospace and serif in madan-fonts.

# fc-match sans:lang=en
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match sans:lang=en-us
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match sans:lang=ne
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match sans:lang=ne-np
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"

For this issue, the above result isn't bad. the reasons why fontconfig didn't pick up Madan font is:

 * madan-fonts doesn't have certain glyph coverages that fontconfig is expecting in ne.orth.

   $ fc-match -v Madan | grep -E "^    ]*lang"
           lang: (s)

 * since the locale-specific overrides rule adds Madan as the weak binding now, Lohit Devanagari has a priority since it appears in 65-nonlatin.conf. 65-madan.conf should be renamed to 65-0-madan.conf or something like that.

# for i in $(ls /usr/share/locale|grep -v -E "^ne$"); do fc-match sans:lang=$i|grep "Madan"; [ $? = 0 ] && echo $i; done
#

No affects to other languages so far. but I'm not really sure when the above issues got fixed once.

Anyway, it's good enough for this issue but need further fixes to make this package useful for Nepali.
