Converts a filename into a valid UTF-8 string. The conversion is
not necessarily reversible, so you should keep the original around
and use the return value of this function only for display purposes.
Unlike g_filename_to_utf8(), the result is guaranteed to be non-
even if the filename actually isn’t in the GLib file name encoding.
If GLib cannot make sense of the encoding of
filename, as a last resort it
replaces unknown characters with U+FFFD, the Unicode replacement character.
You can search the result for the UTF-8 encoding of this character (which is
“\357\277\275” in octal notation) to find out if
filename was in an invalid encoding.
If you know the whole pathname of the file you should use g_filename_display_basename(), since that allows location-based translation of filenames.
A pathname hopefully in the GLib file name encoding.
|The data is owned by the caller of the function.|
|The value is a file system path, using the OS encoding.|
