safe-utf7

npm i safe-utf7

This is a fork of utf7 I (Alison) made to resolve some vulnrablities that were found in the origonal package. I've kept the changes minimal and update the CircleCI confiuration to point to my own instance. What follows are the origonal notes from Konstantin Käfer

utf7

Encodes and decodes JavaScript (Unicode/UCS-2) strings to UTF-7 ASCII strings. It supports two modes: UTF-7 as defined in RFC 2152 and Modified UTF-7 as defined by the IMAP standard in RFC 3501, section 5.1.3

Usage

RFC 2152

var utf7 = require('utf7');

var encoded = utf7.encode('Jyväskylä');
assert.equal('Jyv+AOQ-skyl+AOQ-', encoded);

var decoded = utf7.decode(encoded);
assert.equal('Jyväskylä', decoded);

By default, .encode() only encodes the default characeters defined in RFC 2152. To also encode optional characters, use .encodeAll() or specify the characters you want to encode as the second argument to .encode().

IMAP (RFC 3501)

var utf7 = require('utf7').imap;

var encoded = utf7.encode('"你好" heißt "Hallo"');
assert.equal('"&T2BZfQ-" hei&AN8-t "Hallo"', encoded);

var decoded = utf7.decode(encoded);
assert.equal('"你好" heißt "Hallo"', decoded);

Maintaince Note

I (Alison) am planning to maintain this repositoy, please see the contibuting guide if you have any issues or ideas.
