In addition, the Japanese language will be lost. I think that if you analyze MSN Messenger packets using Ethereal, you know that MSN Messenger 's character code is basically UTF - 8, but internally flagging internally between Japanese clients Is communicating as shift JIS.

But since it is open source software, somehow somehow it will make a version that can display Japanese.
