$ amfora GEMINI.CIRCUMLUNAR.SPACE
53 No proxying to other hosts or ports!
$ amfora gemini.circumlunar.space
[works]

Stéphane Bortzmeyer notes:

RFC 1034, on DNS, in its section 3.1 "By convention, domain names can be
stored with arbitrary case, but domain name comparisons for all present
domain functions are done in a case-insensitive manner, assuming an
ASCII character set, and a high order zero bit." And section 3.5 "Note
that while upper and lower case letters are allowed in domain names, no
significance is attached to the case. That is, two names with the same
spelling but different case are to be treated as if identical."

Also, in RFC 3986 on URI, section 3.2.2 "The host subcomponent is
case-insensitive."

(IDN complicate things a bit and, unfortunately, Gemini standard is
silent about IDN.)
