"will do what you expect" in Lua if such escape is defined with precise semantics (ie. 
accept two and only two hex digits).

That's what I meant.
Semantics of other languages is irrelevant here! ;-) They are important if programmers are 
familiar with them, but they must not get in a way, and the rule above is simple enough 
and probably intuitive enough not to break the beloved (?) "principle of least surprise" 
(surprises can change depending on background of programmer, anyway).
