layout/style/test/test_initial_computation.html layout/style/test/test_value_computation.html fail in Japanese locale, and I suspect in any other locales where the default serif/sans-serif preference differs from Western locales. I thought maybe the underlying problem is that nsPresContext::UpdateCharSet needs to call RebuildAllStyleData() after calling GetFontPreferences, but that doesn't seem to be it. (Though it's possible that it does -- if we ever have any style data to rebuild when UpdateCharSet is called.) Steps to reproduce: LANG=ja_JP.UTF-8 LC_ALL=ja_JP.UTF-8 TEST_PATH=layout/style make mochitest-plain

Could also be another instance of bug 416581.

This seems to be fixed by the patch is bug 416581.

Wait. I ran the command from comment 0 in the wrong tree (one without the patch from bug 416581). Did something else fix this bug?

On what platform? The locale codes for Japanese might be different. Does: LANG=ja_JP.UTF-8 LC_ALL=ja_JP.UTF-8 date produce output like: 2012年 1月 31日 火曜日 15:16:39 CET ?

(And that particular command works on one of my two Ubuntu 11.10 machines and not the other -- and I don't know what the difference is other than guessing it's related to a package that's installed on one and not the other.)

(To be clear, I wasn't able to try the mochitest command, since the one with the development environment is the one where that command doesn't work.)

jwatt$ LANG=ja_JP.UTF-8 LC_ALL=ja_JP.UTF-8 date 2012年 1月31日 火曜日 14時35分16秒 GMT So it seems to work for me. This is on OS X 10.7, recent m-c, debug build created using Xcode 4.2.

Though it's possible that locale stuff on Mac OS X is controlled by something less Unixish than environment variables...
