Subject [jira] [Commented] (TAP5-1778) Template parsing dependent on JVM default charset
Date Wed, 13 Jun 2012 15:34:42 GMT

    [ https://issues.apache.org/jira/browse/TAP5-1778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13294523#comment-13294523

Takeshi Sugita commented on TAP5-1778:

JVM's default encoding has been used to log output or console.
JVM settings, it happens the effect is too large.

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") );
