Fedora: login failed if name contains non-ascii characters

Tried:
JBoss standalone.xml settings (worked):

• <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>

• <property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/>

ServletFilter (does not work):
Set request and response encoding in ServletFilter for openid url, but not working. It only supports POST action for the req/res body but not URI.

Use openid4java library for parsing parameters (worked):

• bypass param encoded with servlet `req.getParameterMap` in openId by using `ParameterList.createFromQueryString(httpReq.getQueryString());` when processing response from openid.

Encoding issue in the library:

Spec for http-charset

Workaround: change the name to contains ascii only
