Mu now has support for Unicode. Just graphemes that map to single code points; no combining characters.

Mu also is starting to gain a fake screen that (interactive) programs can print to in tests.

Here's how it looks: https://archive.org/details/akkartik-2min-2020-09-02

Strings are arrays of bytes. To iterate over the graphemes in a string, store it in a stream and read graphemes from the stream.
