We found that there are difference in screen-displayed multibyte characters on using Internet Explorer and Firefox. When using MS932, with IE, characters are returned same as posted, however with Firefox, characters are url-escaped like %xx. Our guess is that html of jmx-console does not have charset and there are no functions to handle encoding request parameter.

It could be fixed if there were some filter action something like distinguish character set of posted data, and add <meta> tag into html or set Content-Type.
