Garbage characters and slow responsiveness

Hi,
While I enjoy diving into ratpoison usage recently, I also found some
potential issues, which I don't know if others have situations alike.

1. multibyte characters rendered as gargabe in command :windows.
It appears that ratpoison handles UTF-8 alright, because if I enter
`ratpoison -c windows' under console, all the windows' names are output
currently.

here's a screenshot: http://i.imgur.com/Ch2QG.png

These should be chinese characters, which occupy 3 bytes in UTF-8.
Apparently rp doesn't decoded it right because 1 character appear as
exactly 3 gibberish byte in :echo.

2. Slow responsiveness in window switching
With certain types of application (ie firefox), the "other" command
appears either slow in reaction. Sometimes the window requires 1 second
to finish rendering. Don't know if this is Firefox's fault or rp's,
because this doesn't happen with other stacking WMs, for example, pekwm.
