Error with unicode character - python 2.7

[mathisonian]

I had the following line of code, that caused my template to throw an error:

error 'ascii' codec can't encode characters in position...

Line throwing an error:

meta(property="og:description", content="#{post.tldr}")

which could be fixed by

meta(property="og:description", content!="{{post.tldr}}")

Is this expected behavior? post.tldr is a unicode string.

I believe this is caused by __pyjade_attrs using str literals instead of unicode.

This problem may appear again because __pyjade_attrs calls escape which fallbacks to str instead of unicode:
