String literals

beets is very attached to unicode input and output. So when writing code you should follow these guidelines for usage of string literals in beets source:

• All outputs to logging module should be marked with u. (log.debug/warn/info/etc(u'foo')

• Arguments to exceptions: Almost always u. (raise Exception(u'foo'))

• print_ and such: Always u.(print(u'foo'))

• Methods __str__() and __repr__() should always return native python strings (return 'foo')

• URLs and data for HTTP requests: native strings ('foo')

• SQL Statements: native strings ('foo')

• Pieces of filenames: Always b, unless it's in some parts of the destination method before the path is encoded. (b'foo.mp3')
