std::strerror and UTF-8

[Wolfgang Meier]

Hi,

I use a library (libphysfs) that calls std::strerror to return a
human-readable error message. According to the docs I read,
std::strerror will return this error message localized and encoded
according to LC_MESSAGES.

Patching the library is no option, so is there any portable way of
obtaining the error message encoded as UTF-8, e.g. by converting it?

Thanks in advance,

Wolf

What makes you think the returned message is not UTF-8 which is
"backwards compatible with ASCII"? See:
http://en.wikipedia.org/wiki/Utf-8

If, in fact, you do need to convert, look into the GNU iconv library.
It's a widely used, easy to use character conversion library.

Thanks! That did the trick.
