Re: What does it mean to "not be a valid string in Unicode"?

Unicode libraries commonly provide functions that take a code point and
return a value, for example a property value. Such a function normally
accepts the whole range 0..10ffff (and may even return a default value for
out-of-range inputs).

Also, we commonly read code points from 16-bit Unicode strings, and
unpaired surrogates are returned as themselves and treated as such (e.g.,
in collation). That would not be well-formed UTF-16, but it's generally
harmless in text processing.
