Worst case use an adapter range.
And that is better than a plain string?
because its front method does not do any decoding.
If it was a plain string you wouldn't use "front". You would handle any,
possible, decoding by yourself, internally in the lexer. This is what
Johnathan already does, it seems:
static if(isNarrowString!R)
Unqual!(ElementEncodingType!R) first = range[0];
else
dchar first = range.front;
If you're only supporting plain UTF-8 strings you would just do:
char first = range[0];
