There should be no need ... the string is automatically converted to the file system encoding (the same thing as the default C-string encoding). The problem here seems to be that your system is using the default encoding (latin1) and presumably your system is actually using a utf-8 based encoding. Now, the default encoding should be automatically inferred from your operating system's nl_langinfo() function ... but may be set/overridden with the GNUSTEP_STRING_ENCODING environment variable. So you could try setting the environment variable to the encoding you want to use. Better still, you could run your code under gdb and set a breakpoint in the GSPrivateDefaultCStringEncoding() function (base/Source/Additions/Unicode.m) and step through and see if you can figure out why the automatic selection of encoding is not working (so we can improve that). _______________________________________________ Bug-gnustep mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-gnustep
