Philippe and I have got bogged down in a long discussion of how to
parse traces of Unicode strings under canonical equivalence against
non-regular Kleene star of regular expressions. Fortunately, such
expressions can be expected to have very little use. A seemingly simple
example is the regex
The hyphen is not redundant in ISO 3166 that defines primary codes with
variable length (even if ISO 3166 part 1 for now only use two-letter codes).
Sometime in a future, two letters will not be enough even in ISO 3166-1, if
countries continue to split/merge (this does not happen frequently but is
L2/15-145R says:
In CLDR 28, LDML will define a unicode_subdivision_subtag which also
provides validity criteria for the codes used for regional
subdivisions (see CLDR ticket #8423). When representing regional
subdivisions using ISO 3166-2 codes, only those codes that are valid
for the LDML

Isn't it possible for your basic substitution to transform \uf073 into a
character class [\uf071\uf072\uf073] that the regexp considers as a single
entity to check ?
In that case, backtracking for matching \u0F73*\u0F72 is simpler:
[\uF071\uF072\uF073]*\u0F72, as it just requires backtracking
