Encode Base64 / URL Strings & Compute SHA-256 Hashes

Q: Why does standard JavaScript btoa() fail on emojis and non-ASCII text?

Native btoa() only accepts Latin1 characters. UtilForge encodes strings to UTF-8 byte arrays via TextEncoder first so emojis and international scripts never throw errors.

Unicode-safe Base64 and URL encoding paired with hardware-accelerated Web Crypto SHA-256 and SHA-512 digests.
