Re: How to simulate UTF-8 encoded request parameters

Hi,

I have to give this post a second shot, since it really hurts. Maybe
there's somebody out there, who could give me a hint or confirms this
a bug in HTTPUnit?

I want to test a servlet which serves GET requests. Those requests
have parameter values encoded in UTF-8-URL-Encoding.
My problem is, that my servlet under test gets wrongly i.e. ISO-8859-1
decoded request parameter values (by invoking getParameter() on
HttpServletRequest). The values are completely messed up then, of
course.

The attached post has a simple test case to demonstrate this strange behaviour.

Anybody who is familiar with this phenomenon? Any hint is very much appreciated!

Thanks,
Stefan Hübner
