Any decent parser is going to special-case strings (especially if it's using 
slicing), in which case, it won't call front unless it needs to decode. The 
only real question is whether generic char and wchar ranges should be 
supported, because then you could avoid the decoding for ranges that aren't 
strings, but strings are already covered simply by special casing. You really
can't afford to not special-case for strings for algorithms in general if
efficiency is a high priority.
