site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com User-agent: Thunderbird 2.0.0.9 (Macintosh/20071031) I made a small mistake when writing my initial message. I forgot to print the e.what() message when the std::locale ctor throws an exception. I've updated the code in the link to do that. Here's the new output on my OS X machine; as expected, it just says that the locale name is invalid: === BEGING TERMINAL OUTPUT === Trying c locales...

It would be unhappy, but at least settling, if I found a page that said something like "C++ locales on OS X only support "C" and "POSIX", tough luck!". However, such a page is nowhere to be found, and in fact I have found evidence to the contrary. Searching "site:apple.com std::locale" in google brings up various pages where people describe issues with the usage of std::locale. However, these pages pertain to issues with the usage of the locale after it has already been created, which implies that the people who made the posts were actually able to create the locale to begin with; so why am I not able to create them? I've been banging my head against the wall for a while now; any help would be much appreciated -Patrick _______________________________________________ Do not post admin requests to the list.

This email sent to site_archiver@lists.apple.com I have exactly the same problem and it's a rather fatal one in my case. Am i assuming right that i can't use UTF-8 in my application? I'm using a part of the boost library. This is most likely the place where the exception is thrown. It works when i set the default locale of my shell to "C" or "POSIX" but nothing else... I'm relatively unexperienced in working with locales so i don't have the slightest idea Since i can't find very much about this exception i wonder if anyone has solved this problem. smime.p7s
