If you copy a file name from Finder and paste it in a new window or a window with utf-8 encoding (anyway, uf8 is the default!), it breaks it splitting the accent from the letter:

á -> a’

It doesn’t occur if you do everything inside ST2, pasting a á (for example) after copying in from ST2 own: it does fine.

Other text editors have not the same problem. It only fails in ST2
