Doe the Avoka TM Security Manager support Simplify and Traditional Chinese languages for the following items
TM and its Java API support UTF-8 up to the Unicode 3-byte character limit, so yes this will cover simplified Chinese charsets. Traditional Chinese charsets may need to be checked as I believe some characters may exceed the 3-byte Unicode range (U+0000 to U+FFFF).
Some further reading:
Note that your security manager implementation may need to take translation / value mapping into consideration if you find yourself in the unfortunate situation of having SAML attribute values an Chinese and TM Group names in English.
