Right, then we need some good names. I think we should break the
convention established by basic_string. I suggest these:
ecs_text_view, wecs_text_view, utf8_text_view, utf16_text_view,
utf32_text_view. That is assuming the paper that establishes UTF-16 and
UTF-32 as encoding for char16/32_t literals is accepted.

I think we should carefully consider what a modern I/O library should
look like and then design for it. I think I/O should be in terms of
std::byte. I hope integers will be 2s complement soon so serialization
of integers won't be a problem. Since code units are just integers, we
should just work on top of that.
