Any portable way get a filename in UTF-8 or to get the FS encoding ?

Hello,

I am trying to devise a simple tool in which I read many directory and file names (to compare two directories).

I never wrote code that I would port to different systems, but I would not mind doing it now.

So I download and read sus v2 and sus v3 to see the openddir/readdir/closedir functions, but they only return char[] strings for file names and they say nothing about the encoding of the file names.

A computer system may mount and/or access many kinds of file systems. NTFS as I know is an UNICODE file system (Sorry I do not know how ufs or extfs are). When mounting FAT systems one can explicitly specify a charset for all the file names.

I have seen _wreaddir function in some implementations, but is there a portable way to get a file's name in UTF-8 or to get a file name in the underlaying encoding of its file system and to get the encoding ?

Are POSIX implementations required to convert the file name return by readdir to the application's execution character set ?

Thank you,
Timothy Madden,
