Well, it would be useful to find out how come Emacs comes with such a bogus character code in the middle of what is supposed to be pure ASCII text. Can you set a breakpoint in scan_for_column, just before it calls composition_compute_stop_pos, conditioned on scan = 1645, then step inside composition_compute_stop_pos, and see how come it fetches such a character code? Is buffer text being corrupted by something? TIA
