Screenshot of Facebook FQL sample code, when logged in as a Chinese user

Safari version: 6.0
OS X Version: 10.8.1

Summary:

When a <pre> or <code> has lang attribute set to zh, zh-tw or zh-cn, or is inside an element with such lang attribute, then the texts are not in monospace font.

Code to reproduce:

    <pre lang='zh-tw'>hello world</pre>

Expected result:

"hello world" should be in monospaced font.

Actual result:

"hello world" are in sans-serif font.

Test code:

Real-world example:

https://developers.facebook.com/docs/reference/fql/

When logged in a Facebook account with user language set to Chinese (Traditional), the code examples are not in monospace font, but in Heiti TC.

I think this is because Safari now chooses font by the lang attribute, and in Mac OS X, monospace font of zh, zh-tw and zh-cn are the same as sans-serif font, described in DefaultFontFallback.plist (under /System/Library/Frameworks/CoreText.framework/Versions/A/Resources)
