When I browse space using tree view of list pages, confluence doesn't display page name correctly if the page name is in Korean.
I did some trace with the source code and found that the response from confluence is cut before end. I thinks its encoding problem, again.

Confluence(Java) counts a foreign character (utf-8) as 1 character. As you know most of Korean characters are two-bytes. But when we receive the response, only the first half of that character is arrived.

This symptom also occurs when I use pagetree plugin.

Refer to the screenshot-1. If there is a problem with rendering child pages, it always happens at the last one. May be the response was cut according the the byte count not character count.
