Summary
Space bug in `clean_text`
Details

An incorrect mapping from HTML specification to ASCII codes was used. Because HTML treats the Form Feed as whitespace, code like this has an injection bug:

let html = format!("<div title={}>", clean_text(user_supplied_string));

Applications are not affected if they quote their attributes, or if they don't use clean_text at all.
