Sorry, I don't understand: do you mean "non 8-bit wordchars"?  I don't
think 7 bits is assumed anywhere.

Assuming you did mean 8-bit, then why not use UTF-8 for Catalan from
the get-go?  Only some languages can use single-byte encodings, and
evidently Catalan is not one of them.  For that matter, why shouldn't
aspell and hunspell use UTF-8 by default (something I already asked)?

I don't understand what are you trying to accomplish by encoding
OTHERCHARS in UTF-8.  What exactly is the problem with them being
encoded in some 8-bit encoding?  Please explain.
