RFC 2047 Encoder / Decoder for DevToys

An extension tool for DevToys that converts text to and from RFC 2047 encoded-word format.

RFC 2047 is commonly used in email headers for non-ASCII text, for example:

  • Encoded word: =?UTF-8?B?57mB6auU5Lit5Y2c?=
  • Decoded text: 繁體中文

Features

  • Encode plain text into RFC 2047 encoded-word format.
  • Decode RFC 2047 encoded words back to readable text.
  • Toggle between Encode and Decode modes in the DevToys UI.
  • Live conversion while typing.

Current Behavior

This project currently implements the following logic:

  • Encoding:
    • If the input is ASCII-only, the text is returned unchanged.
    • If the input contains non-ASCII characters, the tool encodes the full input as UTF-8 Base64 and wraps it as one encoded word:
      • =?UTF-8?B?<base64>?=
  • Decoding:
    • Supports both B (Base64) and Q (Quoted-Printable-like) RFC 2047 modes.
    • Uses the charset declared in each encoded word and decodes via .NET encodings.
    • Decodes all matches in the input that follow the encoded-word pattern.

Usage

  1. Open DevToys and select RFC 2047 Encoder / Decoder.
  2. Choose conversion mode:
  • Encode: text → RFC 2047 encoded words
  • Decode: RFC 2047 encoded words → text
  1. Enter input in the Input panel.
  2. Read the result in the Output panel.
