/* TODO Add kana, hangul, and other small sahpers here */
/* When adding trivial shapers, eg. kana, hangul, etc, we can either
* add a full shaper enum value for them, or switch on the script in
* the default complex shaper. The former is faster, so I think that's
* what we would do, and hence the default complex shaper shall remain
* empty.
