I would not necessarily be opposed to making ui_fg and ui_bg prefs and adding a bunch of [class]::default_style->[whatever]color() to dillo.cc, although I wouldn't be surprised if we ran into our share of places where fltk hardcodes things to, say, GRAY75.

Finally now I have some time to investigate this bug. I'll start with the problem Johannes described (large jpeg) because of the test-case. Let's start... -- Cheers Jorge.-

Wouldn't it be wrong to wrap after most multibyte chars? (e.g., if you go to uk.wikipedia.org)

To me, it seems like a good thing on the whole... furaisanjin said that doing this makes text in tables too narrow, but I'd imagine that's a smaller matter than the lack of wrapping would be. I think the current patch would fail to work if numeric entities are used to specify characters.

I think the patch for Html_write_raw is rather simple than I thought. If I can give one comment, it's better to treat all multi byte UTF8 characters in the same way (not only Chinese and Japanese) so that more people would be happy. If some people don't want to add this patch for pure ASCII only language, would you able to add prefs control for multi byte UTF8 character languages? Regards, furaisanjin

Thanks for the URL. It was just committed in dillorc, so 2.1 will have it hinted there. -- Cheers Jorge.-

BTW, AFAIR the patch for wrapping chinese is "basic". As I don't know anything about chinese it's very hard for me to evaluate. Corvid: is it worth to push this patch to the repo? Steve: what's your opinion on the patch? Can you improve it? and finally, how are the "sung" fonts installed? (to be able to render chinese here). -- Cheers Jorge.-
