Frequently Asked Questions (FAQ)

Does this prevent XSS?

It helps for text content, but attributes, URLs and scripts each need different handling. Use your framework’s escaping in real services.

Should non-ASCII text be encoded?

Not for UTF-8 documents. Turn on "encode all non-ASCII" only for older systems.
