while() cycle in sm_truncate_string() assumes that strpos/mb_strpos advances to next symbol. In some conditions (mbstring + raw gb2313 text + utf-8 charset used by translation + some PHP version, at least 5.3.13) it does not advance. If you want better explanation, I can split that string into hex codes and try to find what is specific in position which locks the cycle.

You can't use SquirrelMail in Traditional Chinese without a
translation pack, although that might not matter (the problem may not
be related to the presence or lack of the presence of the
translations).
It does not matter if translation files are installed on not. Key is utf-8 charset. You can't reproduce it in iso-8859-1, because all symbols there use only one byte, and you can't reproduce it in euc-jp, euc-kr or other JCK charset used in SquirrelMail, because these charsets use two bytes and don't follow strict formating rules of utf-8.
