docs: def convertToAscii(string, error="?"):
  	"""	Utility function that converts a unicode string to ASCII. This
  		exists so the :class:`Comic` class can be compatible with Python 2
  		libraries that expect ASCII strings, such as Twisted (as of this writing,
  		anyway). It is unlikely something you will need directly, and its
  		use is discouraged.
  
  		Arguments:
  
  			string: the string to attempt to convert.
  
  			error: a string that will be substituted into 'string' wherever Python is unable
  			to automatically do the conversion.
  
  		convertToAscii returns the converted string."""
