Is that implementation smart enough to just return imediatly when converting UTF-8 to UTF-8 (like in glibc, the pointer is just return back, the code in Flocale.c checks this)? I don't see much more to do (the combining code uses 16-bit charcters internally, so converting to UTF-8 and then to 16-bit is needed). One alternative as a last emergency could be to write special code as fallback for at least ISO-8859-x to/from UTF-8, but this seems close to reimplementing Iconv. Actually I find it amazing that implementation can be so slow. On my system, PII 400 MHz, I don't notice any abnormal delay even using the version before my last fix (though I use UTF-8 locale, so maybe that's the reason). //Marcus > If I had to use a Solaris system, I would still want to disable iconv. > > -- > Dan Espen E-mail: [EMAIL PROTECTED] > -- > Visit the official FVWM web page at <URL:http://www.fvwm.org/>. > To unsubscribe from the list, send "unsubscribe fvwm-workers" in the > body of a message to [EMAIL PROTECTED] > To report problems, send mail to [EMAIL PROTECTED] > -- Visit the official FVWM web page at <URL:http://www.fvwm.org/>.
