Unicode support

[dlauc]

Fetching of annotations breaks on non-ASCII chars, I suppose UTF-8 encoding is missing somewhere.

Thanks will investigate. I hadn't tested UTF-8 characters but obviously they are causing a few issues. Thanks for reporting.

I wasn't able to re-create the UTF-8 error. When I added a UTF-8 character in mirador it HTML encoded it rather than UTF-8. I suspect the error your getting was because I was writing to an Servlet output stream which doesn't do UTF-8 conversion. I've changed all the outputs to use the Servlet writer which does encode things correctly as UTF-8.

I would appreciate if you could test this fix and let me know if it works with UTF-8 characters.

Cheers

Glen
