lazy extractors: specify the encoding When building with python3 the unicode characters are not escaped, python2 needs to know the encoding. 2016-02-11 13:49:02 +00:00			`# encoding: utf-8`
Add experimental support for lazy loading the info extractors 'make lazy-extractors' creates the youtube_dl/extractor/lazy_extractors.py (imported by youtube_dl/extractor/__init__.py), which contains simplified classes that only have the 'suitable' class method and that load the appropiate class with the '__new__' method when a instance is created. 2016-02-10 13:01:31 +00:00			`from __future__ import unicode_literals`
