If your point was not what you wrote, then no, I'm sorry, my crystal ball 
unexpectedly broke down (why it didn't foresee its own failure I'll never 
know...). I can't tell what you are thinking, only what you write. 
Sometimes I can guess (like my earlier guess that you meant grapheme, 
rather than glyph) but in this case, if you mean something other than 

"UTF-8 bytes can only represent the first 128 code points of Unicode"

I'm flummoxed.
