actually it is UTF-8.

which also explains the problem with peter's umlauts, because the 
[string( message expects unicode points and not UTF-8 bytes.

(see wikipedia for the gory details)

e.g. the german umlaut "ä" is assigned the unicode point '228'.
so [text2d] expects a message like [string 228( to render the letter.

however in UTF-8, "ä" is encoded as two bytes '195 164'.
since [fudiformat] just outputs bytes, you will get a message [string 
195 164(, which will render as "Ã¤" (unicode points 195 and 164).

at the PdCon09 in [string 83 227 111 32 80 97 117 108 111(, me an maira 
wrote a small vanilla library to convert between UTF-8 and unicodepoints.
it's available on deken as "unicode".
