Note also that saying "gemtexts MUST be in UTF-8" is not
everything. We may (or may be not) also want to mandate end-of-lines
(they can be represented with CR, LF, CR-LF, LS or PS, the last two
being purely Unicode, not present in ASCII) and normalization.
If we go that way, there is an existing standard for Unicode text, RFC
5198 <gemini://gemini.bortzmeyer.org/rfc-mirror/rfc5198.txt>. It
mandates CR-LF and normalization NFC.
