Subject: HTTPClient NameValuePair in UTF-8 problem???

Hello,

When I tried to use HttpClient to query a web site with a "UTF-8" paramter,
it just can't match.

When I tried to "Copy & Paste" the character into that web site, it works,
but failed to use HttpClient.

Is there any problem in HttpClient to handle UTF-8 parameters ???


Web Side: http://www.mandarintools.com/chardict=5Fu8.html
In "Paste in Character", select "UTF-8", and paste =E4=B8=8E, (the UTF-8 of=
 the
previous character is \u4E0E),
 and then "Search by Character".

It should return something ....


The following is my source, please teach me how can I pass UTF-8 query
parameters in HttpClient.
