+## Internationalisation (IRIs, UNICODE, punycode, all that stuff)
+
+Even thought the current Gemini specification doesn't mention anything
+in this regard, I do think these are important things, so I tried to
+implement them in the most user-friendly way I could think of.
+
+For starters, gmid has full support for IRI (RFC3987 --
+Internationalized Resource Identifiers).  IRIs are a superset of URI,
+so there aren't incompatibilities with URI-only clients.
+
+There is full support also for punycode.  In theory, the users doesn't
+even need to know that punycode is a thing.  The hostname in the
+configuration file can (and must be) written with proper UNICODE, gmid
+will do the rest.
+
+The only missing piece is UNICODE normalisation.  gmid doesn't
+do that (yet).

 ## Building
 
 gmid depends on a POSIX libc, OpenSSL/LibreSSL and libtls (provided
