Is your feature request related to a problem? Please describe.
Some programming languages, such as Go, allows unicode letters in identifiers.
Having a complete set of unicode letters in Peppa PEG grammar is tedious and low performant.
Describe the solution you'd like
Extend range to support [\p{L}] in addition to current implementation: [a-f] / [\u{1}-\u{10ffff}].
Since \p itself has already the meaning of "range", there is no need to add a dash specifying the lower and upper.

Describe alternatives you've considered
An alternative way is to provide built-in characters like in pest: UNICODE_LETTERS.
