Yes. I agree and did have a unixlib tree with the 'iconv' stuff in, 
though I accidently deleted it.

I was thinking of porting 'libiconv'[1] but I'm quite fearsome of all 
the multibyte encoding stuff.

The wchar implementation that I'm doing is written to support 
MB_CHAR_LEN of 1, though I'm trying to ensure that the work required to 
support a different MB_CHAR_LEN is restricted to only a small set of 
low-level functions.

I'm basing the work on the libc from FreeBSD-current CVS tree because I 
think deriving from GNU libc is going to overcomplicate the library.

At least if I get the basic wchar functions complete, then we have a 
starting point to further extend if we feel it is necessary.
