Description

See https://arrow.apache.org/docs/cpp/compute.html#string-predicates and below. Since R's base string functions, as well as stringr/stringi, aren't generics that we can define methods for, this will probably make most sense within the context of a dplyr expression where we have more control over the evaluation.

This will require enabling utf8proc in the builds; there's already an rtools-package for it.
