> Please tell me which file I shall trace. Trace? I asume you mean to ask what source code you need to browse and understand what it does? You didn't tell whether you are on X11 (Unix, including Linux, and also Cygwin) or Windows, For X11, you need to look into Pango and fontconfig. For Windows, just pango. As you mention Tahoma specifically, my first guess would be that you are on Windows, as Tahoma is the default UI font on XP, isn't it? One thing that will interest you then is the builtin_aliases table in the file pango/pango-utils.c in Pango. It contains the line: "tahoma = \"tahoma,arial unicode ms,lucida sans unicode,browallia new,mingliu,simhei,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi\"", which means that when GTK+ ask for "tahoma", that alias list then says that it should use mingliu or simhei for Chinese, so I don't know why you get "AR PL New Sung". (Note that entries in the built-in aliases table can be overridden by an explicit pango.aliases file.) So maybe you are on X11 anyway, and it's fontconfig that causes the fallback to "AR PL New Sung"? Note that how font and glyph fallback works in Pango on Windows is not ideal at all. It would be much better if it worked more like on X11, and if the "native" fallback information that Windows itself uses would be taken into consideration, and no explicit alias table (either the built-in or a pango.aliases file) would be needed. There are a couple of bugs open against Pango on Windows for features that work on X11 but not Windows. Unfortunately the concepts and code is rather hard to understand and less documented than one would want, and the code is also ad-hoc to some extent (I take partial responsibility for that myself, of course)... --tml _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
