But their support should be controlled by Lisp programs, not be hard-coded in some low-level C code. The way to access discontinuous ranges of buffer text as a single character sequence needs support in Emacs Lisp before we can map it to the equivalent TS features. > (This of course brings up that someday it might be nice to have Emacs > aware of such multi-modal text and able to switch how you're editing > even inside a single file, but that's a bigger topic.) We have the beginning of this, but have a lot more turf to cover. And currently, what we have uses restrictions.
