[makefilename] can only produce a symbol, so it'll never do what you want 
it to be. [ascseq] (or another similar object) is on the right path, but 
it only extracts bytes, which is only valid for 8-bit charsets like 
iso-8859-1 and such.

UTF-8 is a variable-size charset, which is 8-bit, 16-bit or 24-bit 
depending on the character. I think that it's possible to make a decoder 
abstraction for that using [ascseq] and less than a pageful of objects, 
but I don't know the UTF-8 specification so I can't do this for you.
