std: Disallow bytes 0xC0, 0xC1 (192, 193) in utf-8
Bytes 0xC0, 0xC1 can only be used to start 2-byte codepoint encodings, that are 'overlong encodings' of codepoints below 128. The reference given in a comment -- https://tools.ietf.org/html/rfc3629 -- does in fact already exclude these bytes, so no additional comment should be needed in the code.
