Properly implement the encoding for Mother 2 #3
Description
At the moment, the encoding for Mother 2's text has not been properly implemented. While most of the implementation details are complete, there are some things to be worked out.
Things needed to be considered:
- Leniency of the encoder. Specifically, whether A should automatically be treated as Ａ, or if it should fail encoding. In the game, all characters, including English characters are aligned to a grid. If Mother 2 used Unicode, it would probably use the code points for full-width Latin characters.
