It's purely for conversion, you'd basically use it in place of your
character set tables. However, care must be taken because the input can
become longer, for example for -to-UTF-8 -to-UTF-7 conversion. We cannot
do that in lexer's buffers now, we'd need to reserve some space. We may
need wchar_t.

BTW, charset.c cannot be compiled on older compilers:

../charset.c: In function `map_us_ascii':
../charset.c:269: parse error before `static'
../charset.c:276: `xlate_us' undeclared (first use this function)
../charset.c:276: (Each undeclared identifier is reported only once
../charset.c:276: for each function it appears in.)

Means: you mixed code and declaration. Unsupported before C99. C89 is in
wide use and will remain for some time.
