Frequently Asked Questions

What formats are supported?
URL (percent-encoding), HTML entities, JSON string escaping, Base64 encoding, and RegEx special character escaping.

Escaping is needed to safely include special characters in contexts where they have special meaning — for example, & in HTML must be &, and / in a RegEx pattern needs to be \/ to be treated as a literal character.
