Emojicode allows you to convert ASCII characters into Unicode emojis, and convert them back into plaintext. Since there are many more characters in the Unicode emoji set than there are supported ASCII characters, EmojiCode is able to achieve compression of the string length via a simple reversible algorithm. This also means that typing in random emojis is unlikely to result in meaningful text.
Works great with YouTube video IDs!
