https://bugzilla.novell.com/show_bug.cgi?id=244579 ------- Comment #11 from mfabian@novell.com 2007-02-12 08:09 MST ------- I checked in qt-x11-free-3.3.7/src/kernel/qfontdatabase.cpp whether CMEXSong has all the glyphs required for traditional Chinese. qfontdatabase.cpp line 588 ff: // Han_Japanese { 0x4e00, 0x25EF, 0x3012, 0x3013, 0x30FB, 0x5CE0, 0xFF66, 0 }, // Han_SimplifiedChinese, 0x3400 is optional { 0x4e00, 0x201C, 0x3002, 0x6237, 0x9555, 0xFFE5, 0 }, // Han_TraditionalChinese, 0xF6B1 is optional // OR Han_HongkongChinese, 0x3435, 0xE000, 0xF6B1 are optional { 0x4e00, 0x201C, 0x3002, 0x6236, 0x9F98, 0xFFE5, 0 }, // Han_Korean { 0x4e00, 0 } // Taiwan would be 0x201C, 0x3002, 0x4E00, 0x9F98, 0xFFE5 }; CMEXSong has all of 0x4e00, 0x201C, 0x3002, 0x6236, 0x9F98, 0xFFE5, therefore I see no reason why Qt3 refuses to used that. Even if there are no font substitutions defined using this font, it should already be used by default in LC_CTYPE=zh_TW.UTF-8 because it is the default in fontconfig for that locale. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Qt4: The patch helps if the selected font is "Sans Serif", in that case the correct Chinese font is used. But if the font selected is not "Sans Serif", for example some font which does not support Chinese like "DejaVu Sans", this font is not used at all, only the default sans-serif font for Chinese is used in that case. I.e. there is no difference to the case when "Sans Serif" was requested in the application. But of course there should be a difference: If the application requests "DejaVu Sans", this font should be used for all glyphs it supports. Only for glyphs not supported by this font, for example Chinese, Qt should use fallback fonts. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

But as fixing that doesn't help at all for Qt3 and only fixes part of the problem in Qt4 (which isn't even included in SLES), I think fixing this in fontconfig 2.3.94 on SLES is rather useless. I think we should update to fontconfig 2.4.2 for SLES10-SP2 anyway, i.e. if there is no urgent problem in fontconfig 2.3.94 which needs to be solved before SP2, we should not touch it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Using my test program attached to comment #13 with "DejaVu Sans Mono" with a test string containing Japanese and running in a ja_JP.UTF-8 locale I get: mfabian@magellan:~/cpp/fontbug$ locale LANG=ja_JP.UTF-8 LC_CTYPE="ja_JP.UTF-8" LC_NUMERIC="ja_JP.UTF-8" LC_TIME="ja_JP.UTF-8" LC_COLLATE="ja_JP.UTF-8" LC_MONETARY="ja_JP.UTF-8" LC_MESSAGES="ja_JP.UTF-8" LC_PAPER="ja_JP.UTF-8" LC_NAME="ja_JP.UTF-8" LC_ADDRESS="ja_JP.UTF-8" LC_TELEPHONE="ja_JP.UTF-8" LC_MEASUREMENT="ja_JP.UTF-8" LC_IDENTIFICATION="ja_JP.UTF-8" LC_ALL= mfabian@magellan:~/cpp/fontbug$ fc-match sans meiryo.ttc: "Meiryo" "Normal" mfabian@magellan:~/cpp/fontbug$ I.e. "Meiryo" is the default font for Japanese on my system. But without using font substitutions at all in ~/.qt/qtrc I do not get Meiryo for the Japanese glyphs, I get “MS Gothic” instead: mfabian@magellan:~/cpp/fontbug$ ./fontbug & [1] 13776 mfabian@magellan:~/cpp/fontbug$ grep fonts /proc/$(pidof fontbug)/maps 2ba35d570000-2ba35de1b000 r--p 00000000 03:02 1128589 /local/fonts/vista/msgothic.ttc 2ba35de70000-2ba35deb0000 r--p 00000000 03:01 1101133 /usr/share/fonts/truetype/DejaVuSansMono.ttf mfabian@magellan:~/cpp/fontbug$ If I add a font substitution rule to try “Meiryo” first when DejaVu Sans Mono is lacking glyphs: mfabian@magellan:~/cpp/fontbug$ grep -C 1 DejaVu ~/.qt/qtrc [Font Substitutions] DejaVu Sans Mono=メイリオ^eMeiryo^e arial=helvetica^e mfabian@magellan:~/cpp/fontbug$ then the test program does indeed use “Meiryo” for the Japanese glyphs. I.e. the font substitutions work but without them the fallback font for Japanese is chosen strangely. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=244579 ------- Comment #33 from mfabian@novell.com 2007-03-23 10:40 MST ------- Sorry, I did not interprete my test for qt3 in comment #28 correctly. “Meiryo” is the default font for Japanese for sans mfabian@magellan:~/cpp/fontbug$ fc-match sans meiryo.ttc: "Meiryo" "Normal" mfabian@magellan:~/cpp/fontbug$ *but* “MS Gothic” is the default font for Japanese for monospace: mfabian@magellan:~/cpp/fontbug$ fc-match monospace msgothic.ttc: "MS Gothic" "Regular" mfabian@magellan:~/cpp/fontbug$ (Japanese locale). And, “ mfabian@magellan:~/cpp/fontbug$ fc-match monospace msgothic.ttc: "MS Gothic" "Regular" mfabian@magellan:~/cpp/fontbug$ (Japanese locale). And, “ mfabian@magellan:~/cpp/fontbug$ fc-match monospace msgothic.ttc: "MS Gothic" "Regular" mfabian@magellan:~/cpp/fontbug$ (Japanese locale). And, “DejaVu Sans Mono” is marked as monospace in /etc/fonts/conf.d/40-generic.conf: <!-- Monospace faces --> <alias> <family>Bitstream Vera Sans Mono</family> <family>DejaVu Sans Mono</family> <family>Courier</family> <family>Courier New</family> <family>Andale Mono</family> <family>Luxi Mono</family> <family>Cumberland AMT</family> <family>Nimbus Mono L</family> <family>NSimSun</family> <family>FreeMono</family> <default><family>monospace</family></default> </alias> That means “MS Gothic” is the correct fallback font in that case. The current qt3 behaviour is completely correct here. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I could not reproduce the problem again which I reported in comment #31, I don't get CMEXSong any more but the correct “MS Gothic” instead. I don't know what I did wrong when testing this. I have updated to STABLE again yesterday, maybe there was a problem with the fontconfig caches which was fixed by the SuSEconfig run after the update? Anyway, everything seems to be OK now. Sorry for the extra confusion. Closing as FIXED again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
