If you mean by this that the code point of each character is determined,
then the code point’s UTF-8 code sequence is calculated, and then each 
octet’s hexadecimal (uppercased) string representation is preceded by ”%”, 
then you are correct.

Yes, up to 4 UTF-8 code units per code sequence are specified in the current  
“Unicode Standard, Version 7.0” [1].  Hence “*at least* 6”.

ACK.
