The thing is that we need to be giving the C library strings encoded in
the current locale, not the locale of any particular port, because
that's how library functions will decode the strings internally -- take
the regexec case, for example, recently fixed.

I think that if the CGI script wants to read or write in a particular
locale, either you set the LC_ALL/LC_CTYPE vars, do a setlocale in the
Guile script, or set the encoding on a port.  But that's port encodings,
not something related to scm_{to/from}_locale_string, I don't think...

Of course, in the CGI context, the encoding of any _environment
variables_ is another thorny question, but not one that should depend on
port encodings.

Andy
