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.
