I'll bear in mind for future projects, thank you.

Sounds good!

OK, I will look to ensure this is still possible.

I have reverted the change (thank you) but introduced a deprecation for returning non-(unicode) strings from "publish_string". I feel this is a reasonable step towards having a more intuitive API.

Naming of "publish_bytes" and "BytesOutput" I am not that set on, we can change to "BinaryXXX" if preferred.

Python converts all line-endings to "\n" when opening a file in text-mode (or in string literals), so this should not be an issue. [1] [2]

I tend to agree, "core.publish_string" would be nicer, but there is no way in Docutils to disable applying the default transforms.

Done in [r9201]
