This is a django filter which will create an html mailto link when you use the syntax:

{{ "[email protected]"|encode_mailto:"Name" }}

Results in:

<a href="mailto:[email protected]">Name</a>

Except everything is encoded as html digits.

The encoding is a string of html hex and decimal entities generated randomly.

If you simply want a string encoding use:

{{ "name"|encode_string }}

This was inspired by John Gruber's Markdown project
