What is URL-safe Base64?

A variant that replaces characters that would be reserved in URLs (+, /) with - and _, and omits trailing = padding. Used in JWTs and modern APIs.

Does it support emoji and Devanagari?

Yes. The encoder converts text through UTF-8, so any Unicode character round-trips cleanly.
