Right, which is why I don't like the idea. But you don't need non-ASCII characters to blink an LED or turn a servo, and there is significant resistance to the notion that appending a non-ASCII character to a long ASCII-only string requires the whole string to be copied and doubled in size (lots of heap space used).
But you need non-ASCII characters to display a title of MP3 track.
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.
Several previous comments discuss first option, ASCII-only strings.
