Python binding socket UnicodeEncodeError

When using Lossless Cut, i receive the following python error when the downloaded screenshot filename contains umlaut characters:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 109: ordinal not in range(128)

Socket.send takes a string (not unicode). When Socket.send is called with an unicode string it tries to convert it with the ascii codec converter, resulting in an UnicodeEncodeError?.

Before calling Socket.send the data has to be converted to a non-unicode string (UTF-8 encoded).

Python binding - call Socket.send with non-unicode string

Socket.send takes a string (not unicode).
When Socket.send is called with an unicode string it tries to convert it with the ascii codec converter, resulting in an UnicodeEncodeError?.

Before calling Socket.send the data has to be converted to a non-unicode string (UTF-8 encoded).
