It seems that the test introduced in 3a771d114f0da4dc62747b19c91aa710550af06b only works properly in Debian. There is, at the moment, no C.UTF-8 locale on Arch. (See also [here](http://comments.gmane.org/gmane.linux.arch.general/43880))\r\n\r\nI think my string manipulation functions will probably be ok, since my default locale (which can be queried by `std::locale().name(\"\")` (note the extra `\"\"`)) is `en_US.utf-8`."}}
