Utility for encoding and decoding text using zero-width characters.

Subject text is first converted to its binary representation (e.g. "foo" -> "011001100110111101101111"), then each digit is replaced with a zero-width character (specifically: U+200B and U+200C). Decoding is simply the inverse of the same flow of operations.

As a module:

use zw;
// ...
let encoded = zw::encode("Hello");
let decoded = zw::decode(&encoded);

As a CLI tool:

zw [-e|--encode] [-d|--decode] [input]

If both -e and -d flags are omitted then conversion direction is guessed based on the first interpreted character.

Reads from stdin if an input string isn't provided in its arguments.

# Shell-ish
zw "Hello" > encoded.txt
cat encoded.txt | zw > decoded.txt

# MacOS clipboard encoding
pbpaste | zw | pbcopy
