You said it.  It's difficult to identify the language which a character corresponds to (cf. Latin based scripts such as English French, Spanish, Vietnamese, and so on).  But if you have that information, i.e. whatever identification of the IME used when that character was entered, you will be able to differentiate those languages and adapt the context to the current character.

Actually several languages share some same planes as the Latin script based languages.  For instance Vietnamese takes its characters from 5 different planes.
