> This is my first experience with JIRA, so apologies if it is not formatted 
> properly. I raised this topic on the tapestry-users mailing list and was 
> asked by a couple of people there to create an issue here.
> internal.services.XMLTokenStream's openStream method contains the following 
> lines:
> InputStreamReader rawReader = new InputStreamReader(rawStream);
> ...
> PrintWriter writer = new PrintWriter(bos);
> Both of these implicitly rely on the default JVM charset. This poses a 
> significant problem for non-ASCII text in templates on Google App Engine, 
> where the default is "US-ASCII". In the interests of robustness, I think it 
> would be nice if Tapestry was able to eliminate any reliance on default 
> charsets. I am not confident enough in my understanding of Tapestry internals 
> to know how to appropriately retrieve symbol properties (such as 
> "tapestry.charset") via the IoC system in internal service implementations, 
> but I have verified that explicitly specifying "UTF-8" as follows resolved my 
> problem:
> InputStreamReader rawReader = new InputStreamReader(rawStream, "UTF-8");
> ...
> PrintWriter writer = new PrintWriter( new OutputStreamWriter(bos, "UTF-8") );
