Not surprising, since most people don't set display-raw-bytes-as-hex. 
But that doesn't mean it's not a problem. Quoting bugs can be issues 
even if they're unlikely to occur at random. (Think SQL injection. :-)

That's fine, so let's fix the problem as originally suggested. That is, 
display the string returned by (format "%c%c" #x9e #x66) as "\x9e\x66" 
(equivalent to (concat "\x9e" "\x66") which is correct) instead of as 
"\x9ef" (equivalent to "\N{BENGALI DIGIT NINE}" which is wrong).

This fixes the problem and doesn't introduce new syntax.
