[OSM-newbies] Uploading gpx files: parsing a bit aggressive? UTF-8 only?

[ael]

I have just had a gpx file rejected:-

...failed to import. Here's the error:

   Generic XML parse error
   XML parser at line 1 column 30

And the first line is
<?xml version="1.0" encoding="iso8859-1" standalone="yes"?>.

Playing with an editor, it seems that the problem is "iso8859-1"

   encoding="UTF-8" is accepted.

Is there a reason why iso8859-1 should be rejected? Or does the parser 
need to be modified?
