I am afraid you get confused between Unicode and ISO 3166. Unicode
gives code points for characters, ISO 3166 defines the country code,
and the local language(s) and script(s). This relate to the support
of IDNccTLD not to the support of characters, except when there is a
possible exception due to a difference between a country and Unicode
on a character set. In that case, ISO 3166 should prevail as it is
the basis for every other international applications, standards and UN WSIS.
Just for your information. We are a certain number to acknowedge ISO
3166 as the core building block of multi-lingualisation,
-lateralisation, -achitecture for the Internet. i.e. as its core
element of stability. This from experience, from observation of the
world and because it is a TC46 standard and TC46 respects the ISO
rule to develop clear and interintelligible standards (to proceed in
parallel in English and French). This was underline by Paul about
verbosity in RFCs. A standardisation process should use
bi/trilingualism to reduce pragmatics and augment semantics.

Nous avons une confusion habituelle entre les normes ISO et leur
propos. Ceci vient (1) d'une connaissance plus forte des RFC que des
normes internationales et des grands standards (2) d'un disrespect de
la norme d'écriture des normes ISO en français et en anglais en
parallèle (ce qui devrait permettre de réduire les pragmatismes
propres à chaque langue, et d'augmenter la valeur sménantique par
ajout des pensers des deux langues).
