Original commit message from CVS: * gst/subparse/gstsubparse.c: (convert_encoding), (gst_sub_parse_change_state): * gst/subparse/gstsubparse.h: Text subtitle files may or may not be UTF-8. If it's not, we don't really want to see '?' characters in place of non-ASCII characters like accented characters. So let's assume the input is UTF-8 until we come across text that is clearly not. If it's not UTF-8, we don't really know what it is, so try the following: (a) see whether the GST_SUBTITLE_ENCODING environment variable is set; if not, check (b) if the current locale encoding is non-UTF-8 and use that if it is, or (c) assume ISO-8859-15 if the current locale encoding is UTF-8 and the environment variable was not set to any particular encoding. Not perfect, but better than nothing (and better than before, I think) (fixes #172848).
