In reply to Ronaldo.

Ronaldo, some other readers had the same problem (see other comments). The trick is that the Windows CMD console does not support UTF-8 natively, so one must explicitly set the OEM codepage if you're using non-ASCII characters. You can avoid the characters in your script (assuming these are file paths) by specifying the shorter 8.3 versions of the names. You can discover those names for a given path by issuing "dir /X" at a command prompt.
