Thank you for finding this :-).  With this(ScopedREstoreICUDefaultLocale), you
don't need to have 
split tests into en-US, en-GB and ja-JP.

Cool, grouped them into one test.

An alternative would be 

EXPET_EQ(u8"2011年4月30日", UTF16ToUTF8(TImeFormatWithPattern...));

It turned out that u"...." for UTF-16 string literal is not yet allowed to use
in Chromium tree (There was a thread back in September but no resolution, yet),
but I'm sure 'u8' is allowed.

Done.
