to match/non-match characters belonging to a certain range
or having a certain unicode property.

Provide a negative expression to reject characters that satisfy it.
If both are given a character must match positive (when provided) AND must NOT match negative (when provided).
At least one of the arguments must be provided (throws otherwise).
Use satisfy from core module instead if you need an arbitrary predicate.
