Exactly. If you want bytes, use ubyte[] or byte[] (probably ubyte[]). C++ 
lacks such a proper type (though C99 has uint8_t). char is specifically a UTF-8 
code unit and should be treated as such.

Also, if you have text that you _know_ is ASCII, then it's more efficient to 
cast the string to immutable(ubyte)[] and operate on it that way (so that it 
doesn't do any decoding). That's not currently handled by the string-specific 
functions (though the general array and range-based ones will handle it just 
fine), but I expect that that will change.
