Another issue with Hyperscan is that if you enable HS_FLAG_UTF8[1], which hypergrep does[2,3], and then search invalid UTF-8, then the result is UB.
> This flag instructs Hyperscan to treat the pattern as a sequence of UTF-8 characters. The results of scanning invalid UTF-8 sequences with a Hyperscan library that has been compiled with one or more patterns using this flag are undefined.
That's another issue you'll need to grapple with if you use Hyperscan. PCRE2 used to have this issue[4], but they've since defined the semantics of searching invalid UTF-8 with Unicode mode enabled. ripgrep 14 uses that new mode, but I haven't updated that FAQ answer yet.
