This small fraction needs to organise itself, identify problems in Chinese font/text support, possible fixes, and relay them to upstream projects. For example every year freedekstop.org organises a text summit where pretty much every project that counts in FLOSS text rendering is represented: http://unifont.org/TextLayout2007/ It would be extremely helpful if the Chinese FLOSS user community sent someone to next year's summit to list the main problems affecting Chinese users, and what the Chinese community feels needs to be done in projects like fontconfig or pango to fix them. The rest of the year having clearly identified Chinese relays people can ask questions to (like "if I do this will it break Chinese apps") may probably help too. > The bad lucks of propagating patches back to upstream is also another > reason that discourages Chinese to get involved.

CJK is difficult sure but do not underestimate the part lack of communication plays. Any maintainer will be ultra-cautious about making CJK changes when he knows that if he makes a mistake users are likely not to report back but suffer silently for years while cursing his name. > This also negatively impacts the situation. As a counter example you may have noticed there's been a lot of Greek-related activity on the list lately. It's not because Greek is easier or more interesting that other languages, but because the Greek community managed to organise itself. As a result they're getting good support from every distribution, Fedora included. > As a result, Chinese users HAD to find out work-arounds to meet their > day-to-day needs.

I'll be honest even if someone actively pushes fontconfig changes it may take a year for them to be integrated and yet more time for the changes to percolate in distribution. Getting fontconfig to change is not easy. However if you don't try I'm pretty sure nothing will have changed in 5 years. And you probably need fixes at other levels too. Just like the Wen Quan Yi project is part of the solution, but not the whole solution, fixing fontconfig will probably not be sufficient. For example even if fontconfig selects the perfect Chinese font when told to render Chinese, apps still need to detect they are rendering Chinese, which is not possible basing yourself only on unicode points, or the session locale (though for this particular problem you are better of than Latin languages since you only share codepoints with Japanese) > But there are immediate needs to use Linux in a Chinese-friendly > way and a good work-around can really build up the expanding > user community and likely developer group, and that could > make the life easier in the future. That's my rationale to > push a reasonable fontconfig file for my font. The work-around limits as you've found out is they get removed as soon as someone else complains of them. No one really wants to choose between Latin, Chinese or Japanese users at Fedora, so if two user communities conflict the one stepping on the other loses. By selecting a fontconfig priority of 61 you pretty much removed everyone relying on fonts with a less than 61 priority from the picture. That leaves people relying on fonts with a more-than-61 priority to complain. I suspect some of them, most likely Japanese users, can still be negatively affected by your changes but I'm no Japanese speaker so that's up to Jens to confirm (or infirm). And even if Jens greenlights there is still the possibility of later complains causing to remove your changes. Lastly for Fedora ≥ 9 we'll probably use DejaVu full not DejaVu LGC as default, so you may want to adapt your fontconfig file accordingly in Fedora-devel (you'll note DejaVu full as default got blocked for several releases due to the same kinds of conflicts you're encountering, and is only pushed now we're more confident in its non LGC parts. We try to be fair to everyone) Regards, -- Nicolas Mailhot
