For Unicode it's pretty easy... just look for characters that give  
away the language... for example, Hiragana for Japanese, Hangul for  
Korean, etc.

It's hard to detect all the various encodings... EUC-JP, SHIFT-JIS,  
ISO-2022-KR/JP, BIG5, etc. and many servers do not correctly identify  
the encodings.
