Frequently Asked Questions
What encoding is used?
UTF-8. Each character is converted to its UTF-8 bytes, then each byte is shown as two hex digits.
How is this different from Base64?
Hex uses 0-9 and A-F; two chars per byte. Base64 is more compact. Hex is easier for debugging.
Can I decode any hex string?
Use an even number of hex digits (each byte = 2 digits) and valid UTF-8 for correct text output.
