> Gramps uses the Python version of regular expressions [re — Regular expression operations — Python 3.10.2 documentation](https://docs.python.org/3/library/re.html)

in the documentation you cited, the following note is in the opening section of the docs.

> See also
> 
> The third-party [regex](https://pypi.org/project/regex/) module, which has an API compatible with the standard library [`re`](https://docs.python.org/3/library/re.html#module-re) module, but offers additional functionality and a more thorough Unicode support.

Given that Gramps is heavy in Unicode use (and the recent inquiry about Case Sensitivity not being controllable), is that third-party **regex** more appropriate for Gramps than the standard library **re** module?
