What is the difference between HTML and XML modes?

HTML mode outputs named entities when available, such as ©, while XML mode always uses numeric references so RSS readers and XML parsers accept the result.

Will existing entities be double-encoded?

No. The encoder first normalizes any existing entities before generating new ones so & stays a single ampersand entity.

Does the tool support emoji and other astral characters?

Yes. Astral Unicode characters are preserved whether you encode or decode thanks to the underlying html-entities library.
