Writing GPX error - Githubissues

Hello,

when trying to write a GPX file I get an error.

I found a fix to simply add the encoding "UTF-8" when creating the XMLStreamWriter in the GPX.java class, starting from line 1075:

try {
    final XMLStreamWriter writer = indent != null
        ? new IndentingXMLWriter(
            factory.createXMLStreamWriter(output, "UTF-8"), indent)
        : factory.createXMLStreamWriter(output, "UTF-8");

    writer.writeStartDocument("UTF-8", "1.0");
    gpx.write(writer);
    writer.writeEndDocument();

The error message i got before adding the encoding:

java.io.IOException: javax.xml.stream.XMLStreamException: Underlying stream encoding 'Cp1252' and input paramter for writeStartDocument() method 'UTF-8' do not match.
