The zone identifiers you find in practice are either numeric
(interface indexes) or symbolic interface names, this is also stated
in the description.
The zone index is used to disambiguate identical address
values. For link-local addresses, the zone index will
typically be the interface index number or the name of an
interface. If the zone index is not present, the default
zone of the device will be used.
in other words, its 'not usually very long' but there is not concrete
restriction. Note that the interface name leaf in RFC 8343 also has no
restriction.
