Just to be 100% sure, I checked my patch with utf-16 encoded gpx file, and
it works very well.
Where do you see a problem? is it:
1) when we check the "magic number" of the file, we should differentiate
between utf-8, utf-16 encodins?
2) when we actually parse the gpx file?
3) something else?
Number 1 is indeed a problem, but it is solved by removing the magic number
check for *.gpx files.
Number 2 is not a problem. The file is parsed in gpx.c using the xml library
expat, which is responsible for most of the xml related headaches, including
proper character encoding and decoding for utf-8, utf-16, etc.
gpx.c reads bytes, feeds them to expat, and gets back parsed and re-encoded
utf-8 strings.
But maybe you meant something else?
Hopefully not...
