"Default language" is selected on Localization preferences panel even when language has been set

[Ryan J Ollos]

This is a regression from #11813 / [13323]. The Default language is always selected on the Localization preferences panel even when a language has been set. The following will fix the issue:

I'm unsure how to interpolate the string to get

'<option selected="selected" value="zh_TW">中文 (台湾)</option>'

rather than

'<option selected="selected" value="zh_TW">\u4e2d\u6587 (\u7e41\u9ad4\u4e2d\u6587,\u53f0\u7063)</option>'

Calling print outputs characters rather than escape sequences:

>>> Locale.parse('zh_TW').display_name
u'\u4e2d\u6587 (\u53f0\u6e7e)'
>>> print Locale.parse('zh_TW').display_name
中文 (台湾)

Fixed failing test in [13668] by removing test for the unicode characters.
