I had try other language pack already. But I think this issue is not related to the language pack.
In the Host/Language page has a combo box can display the language name. I read the source code of the page about the combo box when I select . The correct combo box will use HTML code:
<option value="zh-CN">中文(中华人民共和国)</option>
<option value="zh-HK">中文(香港特别行政區)</option>
<option value="zh-SG">中文(新加坡)</option>
<option value="zh-MO">中文(澳門特别行政區)</option>
<option value="zh-TW">中文(繁體) (中華民國)</option>
<option value="ja-JP">日本語 (日本)</option>
but the error page's html code became:
<option value="zh-CN">銝剜?(銝剖?鈭箸??勗???</option><option value="zh-SG">銝剜?(?啣???</option><option value="zh-MO">銝剜?(瞉喲??孵銵?)</option><option value="zh-TW">銝剜?(蝜?) (銝剛瘞?)</option><option value="zh-HK">銝剜?(擐葛?孵銵?)</option><option value="ja-JP">?交隤?(?交)</option>
It looks like the correct page has the "enter" but error page doesn't.
Is there something I can do to verify this case? (I am not the only person meet this issue in Taiwan. Other people in Taiwan have the same problem too.)
ps: I am using the Chinese Traditional platform.
