Bug 7865 – Arial Unicode MS rendering error in Chinese

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: Layout and Rendering

[hlb]

The following css rules show correct result:

font: 100%/1.5 geneva,'Trebuchet MS',verdana,sans-serif;

Ths following css rules can't render correctly. It render correctly in the default size. But if I resize the font size in Safari, it show many boxes only:

font: 100%/1.5 geneva,'Trebuchet MS',verdana,'Arial Unicode MS',sans-serif;

Created attachment 7309 [details]
a test that works

I cannot reproduce this problem with the attached test case. <http://hlb.yichi.org/blog/2006/03/18/65> also renders fine for me (and yes, I do have Arial Unicode MS installed).

I have used another css rule after noticing this error, so the URL do not render with errors anymore.
But, I can't reproduce the problem now, and do not know the reason at all. :-/
I build a page for later testing:
  http://hlb.yichi.org/test/safari/

I reproduce the error: 
http://hlb.yichi.org/test/safari/font3/

[Alexey Proskuryakov]

I still cannot reproduce :(

[hlb]

Can't you see the error, or can't you reproduce another one?
It only happens with Arial Unicode MS combined with other fonts.

I mean, <http://hlb.yichi.org/test/safari/font3/> renders perfectly fine on my machine, although I do have Arial Unicode MS installed.

I can't reproduce either, alexey, i propose a resolution invalid, what do you think?

[Nicholas Shanks]

Can the reporter please attach screenshots of the correct behaviour and the buggy behaviour?

Hello, these are the screenshots for http://hlb.yichi.org/test/safari/font3/ & http://hlb.yichi.org/test/safari/font3-correct/ :

Reporter, what happens if you:
1) copy/paste the box character to UnicodeChecker <http://earthlingsoft.net/UnicodeChecker>;
2) iterate through all the fonts in the list at the top of the window (these are fonts that claim to have the character you have copied)?

One or more of the fonts may have a box glyph instead of the correct one.

[hlb]

Hello Alexey,

Maybr it is not WebKit's fault but OSX. I tried UnicodeChecker. They are all correct Unicode characters.
I tried to clear the font cache ( by Yasu ), and it rendered correctly. But everytime I clear the cache, the problem will be back after several days/weeks. I can't figure out why.

[Alexey Proskuryakov]

So, none of the fonts that UnicodeChecker proposes for these character displays a box glyph? That might actually indicate that the problem is in WebKit (if it were just the OS font cache, I'd expect the problem to be visible in all applications). 

Wherever the problem is, I encourage you to also file a bug with Apple at <http://bugreport.apple.com> (free registration required). Please mention this Bugzilla report, and then post the resulting bug ID here, to ease bug tracking.

I cannot confirm this bug as well. So WORKSFORME.
