From a technical aspect, does the FT infrastructure support the various language fonts?

Example, some websites use "non-standard" fonts to represent the Thai language. Internet Explorer seems to always want to default to Angsana as the standard font type for Thai text. However, the website may have been encoded with another "non-standard' font. Thus, instead of readable Thai, I get some kind of gibberish.

Would the FT infrastructure support the various language fonts? How much of a change would that require? Is it even possible?
