Draw a glyph from a font to implement case conversion, property mapping ? I don't know how can you do that.

That is my quetion DOES it define so. I don't have the access to THE specification itself and asking help to get one. Do you have the
access to the specification and DOES it specify so?

I am not complain on the list. I am asking for confirmation about what is in the specification.

Thanks for provide me such information, although I havce no clue what does "16#1E248#" mean here. I assume it mean 0x1e248, is that
true.
