SPIonic is a public domain font that represents ASCII characters as Greek letters and diacritics. It uses a
scheme based on Beta Code with a few variations, the most significant of which is that uppercase letters are
represented by uppercase letters and lowercase by lowercase (whereas Beta Code uses
*A for uppercase alpha and
lowercase alpha). This tool will convert Greek written using this scheme into Unicode Greek characters.
If you encounter technical difficulties or limitations, please let me know so I can make improvements.
