I wrote that to describe the general considerations, not necessarily because I think they are applicable in this particular case. I didn't analyze the sequences to see whether any of what I wrote can or should be used for them. > One thing though: the code currently does set-char-table-range to a > new value. Is there a chance that an entry already exists in > composition-function-table for a particular character? Only if the non-leading character is a combining character, which I think is unlikely. But in general, yes, this should be tested up front to avoid losing composition rules.
