With a custom one yes. You can use the static method
org.apache.lucene.queryParser.QueryParser.escape(String s).
public void handleRequestBody(SolrQueryRequest req, SolrQueryResponse rsp)
throws Exception, ParseException, InstantiationException,
IllegalAccessException
{
String q = req.getParams().get(CommonParams.Q);
ModifiableSolrParams solrParams = new ModifiableSolrParams(req.getParams());
solrParams.set(CommonParams.Q, QueryParser.escape(q));
req.setParams(solrParams);
super.handleRequestBody(req, rsp);
}
With this solution users cannot use solr query syntax anymore. For example
range, wildcard queries won't work.

May be you can try to parse value of q parameter with new QueryParser in try
catch block. If exception occurs you can escape special characters.
However I would prefer to do it in client side.
