reasons:
* gconvert strdup()s the original string, but it may exit without returning or freeing it.
* gconvert returns the original pointer when no % escaping is done. It is then free()ed and used in that state.
* gconvert doesn't consider that % may be at the end of the string and could continue parsing past the end.
* gconvert would try to free() pointer that iconv() have modified.
* gconvert would try to convert filenames from utf-8 to iso8859-1.
Seems like no other DnD programs convert to utf-8 and/or honors CHARSET.
Not converting seems to work best. Fix it if problem arises.
