MIME Encoding API
The email and MIME text encodings that general base64/hex toolkits leave out. The quoted-printable endpoint encodes and decodes Quoted-Printable (RFC 2045) — the Content-Transfer-Encoding that keeps mostly-ASCII text readable while escaping everything else as =XX hex, with the soft line-wrapping at 76 columns and trailing-whitespace handling the spec requires. The encoded-word endpoint encodes and decodes RFC 2047 encoded-words — the =?UTF-8?Q?…?= and =?UTF-8?B?…?= form used to carry non-ASCII text in email Subject, From, To and other headers — in either the Q (quoted-printable-style) or B (base64) variant, and decodes any mix of them back to plain text. Everything is UTF-8 and computed locally and deterministically, so it is instant and private. Ideal for building and parsing email (SMTP/IMAP), .eml and MIME tooling, newsletter and transactional-mail systems, and migrating legacy mail data. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. These are the MIME-specific encodings; for base64, base32, hex, URL and HTML entity encoding use a general encoding API.
