A python markdown extension for automatic typographic tweaks :

• Avoid widows by adding a non-breaking space between two last words inside each block element (works correctly even with inline tags around those words).
• Replaces " " with « »
• Replaces --- and -- with em and en dashes
• Fixes spacing around punctuation to match classic french typographic rules

Compatible with django.contib.markup, use {% var|markdown:"safe,typografix" %} and have the extension in your path.

To do:

• Configuration for other languages
• Testing code
• Support for smileys
