A rune has nothing to do with UTF-8. A rune stores the codepoint which is totally independent of any encoding (like UTF-8, UTF-16, UTF-23, EBCDIC, whatnot). A rune is an integer, the number of the codepoint. An integer is stored in a certain number of bytes. Asking "So the rune will still occupy 4 bytes, even if the last byte holds no data?" is like asking "So the number 12 will still occupy 8 bits, even if the last 5 bits hold no data?". Yes. An integer is stored in 8 bytes (64bit architecture) and this is true even for "small" integers which would "fit" into one byte. A rune is an integer. It has nothing to do with UTF.
