The source for the Javascript language detection code can be seen here:
http://xpra.org/trac/browser/xpra/tags/v0.16.x/src/html5/include/xpra_client.js#L424

It may need improving so I have created a ticket for this:
http://xpra.org/trac/ticket/1147
Feel free to subscribe to that ticket to get notified of progress / testing.

I couldn't reproduce this with IE until I changed the scaling of the
window. This is now fixed in:
http://xpra.org/trac/changeset/12149
And will be included in the next stable update.

Thanks for reporting those issues.
