Tools (5)

url_codec
URL-encode or URL-decode a string. Use 'component' for values that go inside a query param.
hex_codec
Convert text to/from hex. Encode turns bytes into 2-char groups; decode expects even-length hex.
base64url_codec
Base64URL variant (URL-safe alphabet, no padding). Different from standard base64 — use this for JWT payloads.
gzip_codec
Compress or decompress a string with gzip. Returns base64 for compressed output so it fits in JSON.
unicode_inspect
Inspect a string character-by-character: codepoints, UTF-16 length, UTF-8 byte length. Useful for debugging emoji/RTL/hidden-character bugs.
