# Most people use some kind of ad blocker, and personally I'm using "AdGuard for Safari" which allows you

# 
# Simply add this to AdGuards "User filter", and any wikipedia article will be redirected to Wikiwand.

DataURI.py

Data URI manipulation made easy.

This isn't very robust, and will reject a number of valid data URIs. However, it meets the most useful case: a mimetype, a charset, and the base64 flag.
