How it works

UTF-8 firstText is turned into UTF-8 bytes before encoding, so non-English text and emoji survive the round trip.
URL-safe Base64Decoding also accepts the URL-safe alphabet with - and _.

Is Base64 encryption?

No. It only changes how bytes are written. Anyone can decode it.

When do I URL-encode?

When a value goes inside a URL, like a search query, so characters like & and spaces do not break it.
