Here is a proposal for switching from PCRE to PCRE2. This should close Bug

The patch applies to the default branch of the repository. All 122 BISTs in
regexp.cc pass successfully.

Notice that the compilation fall back to the older PCRE library, in the case
where it is present and PCRE2 is not. This would make the code quite
convoluted and it would represent too much effort for a minimal gain. Indeed,
PCRE2 is now ubiquitous nowadays and the upstream authors have abandoned
development and maintenance for PCRE. Major Linux distributions, like Debian
and Fedora, have plans to completely switch from PCRE to PCRE2 in a future
