In a script window I wrote a script with an accented character. e.g. "Recaudación". Select that string, hit ctrl-c, ctrl-v and the following appears in the script window: "RecaudaciÂ³n". The problem appears to be on copying rather than pasting, given that copying the last string ("RecaudaciÂ³n) yields "RecaudaciÃƒÂ³n" on other windows programs.

ps. Should I keep sending these kind of bugs if I come across them? They might take away time for more important issues.
