Questions
Is Base64 encryption?
No. Base64 only turns bytes into safe text characters so they can travel through email, JSON or URLs. Anyone can decode it, so never use it to hide passwords.
What is URL-safe Base64?
A variant that uses - and _ instead of + and / and drops the = padding, so the result can be placed in URLs and file names without escaping. JWT tokens use it.
Does it handle emoji and Cyrillic?
Yes. Text is encoded as UTF-8 first, so any language and emoji round-trip correctly.
