Sure, but there ARE still bugs in libiconv on Cygwin -- specifically: - Even though iconv_open has been opened explicitely with "UTF-8" as input string, the conversion still depends on the current application codeset. That doesn't make sense. and - 'iconv_close ((iconv_t) -1);' crashes the application with a SEGV. -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
