*
* Patterns are named so that we know which one matched (https://pcre.org/current/doc/html/pcre2syntax.html#SEC23).
* This name is used to "switch" to the additional logic required to match the final route.
*
* Condition-less paths are put in a static array in the switch's default, with generic matching logic.
* Paths that can match two or more routes, or have user-specified conditions are put in separate switch's cases.
*
* Last but not least:
* - Because it is not possible to mix unicode/non-unicode patterns in a single regexp, several of them can be generated.
* - The same regexp can be used several times when the logic in the switch rejects the match. When this happens, the
* matching-but-failing subpattern is excluded by replacing its name by "(*F)", which forces a failure-to-match.
* To ease this backlisting operation, the name of subpatterns is also the string offset where the replacement should occur.

*
* Patterns are named so that we know which one matched (https://pcre.org/current/doc/html/pcre2syntax.html#SEC23).
* This name is used to "switch" to the additional logic required to match the final route.
*
* Condition-less paths are put in a static array in the switch's default, with generic matching logic.
* Paths that can match two or more routes, or have user-specified conditions are put in separate switch's cases.
*
* Last but not least:
* - Because it is not possibe to mix unicode/non-unicode patterns in a single regexp, several of them can be generated.
* - The same regexp can be used several times when the logic in the switch rejects the match. When this happens, the
* matching-but-failing subpattern is blacklisted by replacing its name by "(*F)", which forces a failure-to-match.
* To ease this backlisting operation, the name of subpatterns is also the string offset where the replacement should occur.
