Yes, but to display a title, you don't need to do codepoint access at random - you need to either take a block of memory (length in bytes) and do something with it (pass to a C function, transfer over some bus, etc.), or *iterate in order* over codepoints in a string. All these operations are as efficient (O-notation) for UTF-8 as for UTF-32. Some operations are not going to be as fast, so - oops - avoid doing them without good reason. And kindly drop expectations that doing arbitrary operations on *Unicode* are as efficient as you imagined. (Note the *Unicode* in general, not particular flavor of which you got used to, up to thinking it's the one and only "right" flavor.) > Agreed.
