parser fail at escaped glyphs like �

[mote0230]

Data in gephi:
foobar 🌴
Gives when exported to gexf something like:
<attvalue for="v-name" value="foobar &#xd83c;&#xdf34;"></attvalue>

The parser fails at those escaped glyphs and renders nothing, throwing an error in the console.

Hello.
First, sorry for the late reply.
Browsers don't consider your code as valid XML, so Gexf-JS can't do anything as it uses browsers' in-built parsers.
HTML-style numerical entities are not recognized in basic XML, but normally all UTF-8 characters are valid. If you replace it by the glyph itself, it should work (it does on FF at least):
<attvalue for="v-name" value="foobar 🌴"></attvalue>
