Description Akira TAGOH 2010-03-30 03:52:30 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:
 67-samyak-devanagari.conf
 67-samyak-gujarati.conf
 68-samyak-malayalam.conf
 67-samyak-oriya.conf
 67-samyak-tamil.conf

No explicit rules for monospace and sans-serif in samyak-fonts.

# fc-match serif:lang=en
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=en-us
DejaVuSerif.ttf: "DejaVu Serif" "Book"

That looks good.

# fc-match serif:lang=brx
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=brx-in
DejaVuSerif.ttf: "DejaVu Serif" "Book"

Because fontconfig doesn't have the orth file for Bodo.

# fc-match serif:lang=doi
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=doi-in
DejaVuSerif.ttf: "DejaVu Serif" "Book"

Same reason for the above. no orth file for Dogri.

# fc-match serif:lang=hi
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=hi-in
Samyak-Devanagari.ttf: "Samyak Devanagari" "Regular"
# fc-match serif:lang=kok
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=kok-in

# fc-match serif:lang=mai

# fc-match serif:lang=mai-in
Samyak-Devanagari.ttf: "Samyak Devanagari" "Regular"
# fc-match serif:lang=mr
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=mr-in
Samyak-Devanagari.ttf: "Samyak Devanagari" "Regular"
# fc-match serif:lang=ne
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=ne-np
Samyak-Devanagari.ttf: "Samyak Devanagari" "Regular"
# fc-match serif:lang=sa
Lohit-Devanagari.ttf: "Lohit Devanagari" "Regular"
# fc-match serif:lang=sa-in
Samyak-Devanagari.ttf: "Samyak Devanagari" "Regular"

ll v.s. ll-cc issue. if you want to give a priority to samyak-fonts, you can rename 67-samyak-devanagari.conf to 65-0- and so on.

# fc-match serif:lang=ks
PakType_Naqsh.ttf: "PakType Naqsh" "Regular"
# fc-match serif:lang=ks@devanagari
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=ks-in
PakType_Naqsh.ttf: "PakType Naqsh" "Regular"
# fc-match serif:lang=ks-in@devanagari
PakType_Naqsh.ttf: "PakType Naqsh" "Regular"
# fc-match serif:lang=sd
PakType_Naqsh.ttf: "PakType Naqsh" "Regular"
# fc-match serif:lang=sd-in
PakType_Naqsh.ttf: "PakType Naqsh" "Regular"
# fc-match serif:lang=sd-in@devanagari
PakType_Naqsh.ttf: "PakType Naqsh" "Regular"

fontconfig doesn't take care of @scriptname so far. plus, paktype-fonts has a priority.

# for i in $(ls /usr/share/locale|grep -v -E "^(brx|doi|hi|kok|ks|ks@devanagari|mai|mr|ne|sa|sd)$"); do fc-match serif:lang=$i|grep "Samyak Devanagari"; [ $? = 0 ] && echo $i; done
#

That may be not reliable enough since other fonts is used in some cases. anyway overall of the testing result against this issue looks good.

Testing result for samyak-gujarati-fonts:
# 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 serif:lang=en

# fc-match serif:lang=en-us
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=gu
Lohit-Gujarati.ttf: "Lohit Gujarati" "Regular"
# fc-match serif:lang=gu-in
Lohit-Gujarati.ttf: "Lohit Gujarati" "Regular"

Without lohit-gujarati-fonts:
# 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=gu
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
# fc-match monospace:lang=gu-in
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
# 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=gu
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match sans:lang=gu-in
DejaVuSans.ttf: "DejaVu Sans" "Book"
# 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=gu
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=gu-in
DejaVuSerif.ttf: "DejaVu Serif" "Book"

The fontconfig cache seems not updated properly. fc-cache /usr/share/fonts/samyak/samyak-gujarati didn't help. I had to run fc-cache -f /usr/share/fonts/samyak.

This may be a bug in fontconfig. or may be good to have a workaround in fontpackages to allow putting the font in subpackage under /usr/share/fonts/<fontname>.

Anyway, once getting the correct cache:
# 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=gu
Samyak-Gujarati.ttf: "Samyak Gujarati" "Regular"
# fc-match monospace:lang=gu-in
Samyak-Gujarati.ttf: "Samyak Gujarati" "Regular"
# 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=gu
Samyak-Gujarati.ttf: "Samyak Gujarati" "Regular"
# fc-match sans:lang=gu-in
Samyak-Gujarati.ttf: "Samyak Gujarati" "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=gu
Samyak-Gujarati.ttf: "Samyak Gujarati" "Regular"
# fc-match serif:lang=gu-in
Samyak-Gujarati.ttf: "Samyak Gujarati" "Regular"
# for i in $(ls /usr/share/locale|grep -v -E "^(gu)$"); do fc-match serif:lang=$i|grep "Samyak Gujarati"; [ $? = 0 ] && echo $i; done

That looks good. so please note that if you want to give a priority to Samyak Gujarati, you need to rename 67-samyak-gujarati.conf to 65-0- to avoid 65-nonlatin.conf overrides.

Comment 5 Akira TAGOH 2010-04-23 08:22:09 UTC
