malformed URI sequence

Hello,
        I am using GWT 2.5.1 version. In my project, I have a case where if the user enters locale parameter other than the supported languages we are showing a default language which is english(en). For getting the locale parameter, I am using com.google.gwt.user.client.Window.Location.getParameterMap.If the user enters '%' special charater in the locale parameter from the url then, the getParameterMap() method (com.google.gwt.user.client.Window.Location.getParameterMap) is throwing some exception.The below is the exception thrown by the getParameterMap() method.



com.google.gwt.core.client.JavaScriptException: (URIError) @com.google.gwt.http.client.URL::decodeQueryStringImpl(Ljava/lang/String;)([string: '%']): malformed URI sequence

Now, How can I get the parameters from the url using gwt irrespective of any special characters.


Thanks & Regards,
