Frequently asked questions

Should Korean text be converted to entities too?

If the HTML is saved as UTF-8, Korean text can stay as is. Only < > & and quotes inside attribute values must be escaped.

What are the two parts, like \uD83D\uDE00?

Large characters like emoji are represented as two units (a surrogate pair) in UTF-16. Decoding merges them back into one character.
