Closes #57

LGTM!

I’m curious, what’s your specific motivation for adding support for these?

For what it’s worth, this will be very useful for MapLibre to detect viramas in order to correct the behavior of the ICU segmenter when segmenting text by grapheme cluster.

Nguyễn is right. The node-unicode-data is used by MapLibre.

I think eventually we may just export all data from UCD. IMO the #14 is no longer relevant because thanks to the encoded ranges, the unicode-17.0.0 package is only 1.9MB extracted, way smaller than the the size 108MB of then unicode-6.3.0 package.

I agree.
