> Key: WW-2412
> URL: https://issues.apache.org/struts/browse/WW-2412
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.11

> Reporter: StarBreeze

> There is no activity on WW-826 and I cannot reopen it, so I am creting new
> issue.
> Struts include tag uses the FastByteArrayOutputStream class that copies
> content of included JSP into the response stream by constant sized char
> blocks.
> But UTF-8 symbols have different length in bytes. You cannot split a byte
> stream until you exactly know lengths of it char parts (in bytes).
> As alternative, you may copy bytes, but DO NOT DO new String(bytes, encoding).
> Seems the second approach is not applicable to the char's http response.
> There is the good patch already: http://jira.atlassian.com/browse/JRA-13866
> It solves the problem.
> The bug can be reproduced by rendering a large (>8KB) block of non ANSI
> symbols in the included JSP (JSP must be included by the struts include tag).
> Both parent and included JSPs must have contentType="text/html;
> charset=UTF-8".
> In this situation you may see two garbage symbols on the joint of two buffer
> rendering result. Looks very unpleasant..
