Labels (not "any string") which happens to be pure ASCII
are still case insensitive, which is DNS.

Note that, according to Valdis;

: (The actual policy for the .UA registrar is more subtle.
: They *do* in fact allow "U+0441 Cyrillic Small Letter ES"
: which is visually a C to us Latin-glyph users.  However,
: they require at least one character that's visually unique
: to Cyrillic in the domain name.  They also don't allow
; mixed Cyrillic/Latin scripts in one domain name).

a label (not "domain name") of a Ukrainian word all the
characters of which have shapes identical to some ASCII
characters can only be represented using ASCII characters
