Some sites and services restrict some zero width characters so saving the zero width may be an issue. To get around this, certain limited algorithms have been created which avoid using the restricted characters.
Version 1.2 is the current default algorithm. It supports Cyrillic characters (exp. русский) & Hiragana (exp. ひらがな), and is signed with the version number so it can be automatically detected and de-obfuscated on the screen.
