This hint is mostly for users using high ASCII characters like (?Å¡??žýáÃé).
It applies to some Carbon/Cocoa applications and font combinations. When you try to copy accented text from some Cocoa applications to some Carbon ones (like from Adium to Entourage) via the cliboard, accented characters are messed up.
like from Adium to Entourage
The easy fix is to copy text via drag and drop, not the clipboard. I'm not sure whether some font preference could also fix it.
