I don't know much about filters, but this looks like it is a problem on your
client side, yes. I would recommend instead of building a long string by
hand, you build your query string with:
OpenLayers.Util.getParameterString({'FILTER': filterValue})
etc.
This function will handle the encoding the parameter pieces for
you (and makes your code cleaner to boot).
