1.I have never found suitable Japanese font(style,free of cost,no open source license)
2.I can't download Japanese 'fotw.mo' file because of http 500 err.I could DL it before a month,and can DL other language's file (German for example) now. https://pootle.red-redemption.com/ja/fotw-public/ja.po/export/mo
3.Automatic line break function is not active,so long messages are not displayed correctly.
