Hello
Surprisingly enough, C++ file-based streams can be opened with a char * string (for the filename) only, while modern computer systems have Unicode filenames.
All of them but Microsoft Windows support UTF-8.
How would I let the file-stream object know that the filename to be opened is encoded in UTF-8 ?
It is assumed to be in the locale of the system. Most POSIX systems use a UTF-8 locale these days, but if you really want to be portable, you should convert that.
How ?
If user enters an Unicode filename (with Korean characters) for me to open, and the current locale is Latin 2, how would I open the file ?
On Windows, convert from UTF-8 to wide characters when calling system calls. On other operating systems, pass UTF-8 to the system calls, or convert them to the locale if you care enough about non-utf8 locales.
