どうもありがとうございます。

I noticed two font problems in TeX Live Manager on Windows
(C:\texlive\2010\bin\win32\tlmgr-gui.vbs).

1. The first one is a little problematic in which the main menu of
    tlmgr shows raw utf codes in digits. It looks like:
          \x{30aa}\x{30d7} ... and so on.
    Other parts (e.g. submenus and labels) seem fine.

2. The other problem is aesthetic one. The font used for labels
    seems only for Latin languages and its Japanese presentation
    looks crappy. Can this be changed to pick up system fonts so
    that it becomes one of de-facto standard fonts, such as MS
    UI Gothic in Windows and Fixed font in Unix for Japanese
    on screen? Submenus of tlmgr are presented fine (I think
    MS UI Gothic is used over there).
