Include character data #3
Description
SILE uses this character set data that it extracted from LaTeX somewhere, but I think the essence of this data is probably originally and more canonically in the CLDR data somewhere. Figure out where that is and see if we can extract it in a useful way. Note the copy in SILE is 2MB of source, so this might be a good time to introduce some testing to make sure we balance storage vs. load speed. Does serializing or compressing the data help in any way?
