Technically it is MoarVM that handles graphemes as synthetic codepoints.

We call it NFG for Normalized Form Grapheme.

The JVM and JavaScript backends currently use the built-in string handling features. Which means that they are just as broken as the rest of the code running on them.

Of further note, you can use ignorecase in regexes to match "baffle".

    "baffle" ~~ /:ignorecase  BAFfLE  /;
