the question is, do they really need to know what it means? these are unicode codepoints, they're not likely to change, and `UTF8_RIGHT_TO_LEFT_1` is just as meaningless as `0xE2` unless the context is provided (eg, it occurs in an array named utf8RightToLeft or something)

But yeah, it's unlikely that as a programmer you'll be individually checking each of these bytes, and so they most likely don't need to exist.
