Frequently asked questions

JSON vs JS escaping — what's different?

JSON only allows double quotes and uses \uXXXX for control chars. JS also supports single quotes and \xNN. Pick the target that matches where the string will live.

What about HTML entities?

Use XML escape — it handles the five predefined entities (& < > " ') that are safe in both XML and HTML.

Does it handle multi-byte characters?

Yes. JS escape mode produces \uXXXX for all non-ASCII characters, so the string round-trips through any encoding.
