grep: do not enter PCRE2_UTF mode on fixed matching
As discussed in the last commit partially fix a bug introduced in b65abcafc7 ("grep: use PCRE v2 for optimized fixed-string search", 2019-07-01). Because PCRE v2, unlike kwset, validates its UTF-8 input we'd die on e.g.: fatal: pcre2_match failed with error code -22: UTF-8 error: isolated byte with 0x80 bit set When grepping a non-ASCII fixed string. This is a more general problem that's hard to fix, but we can at least fix the most common case of grepping for a fixed string without "-i". I can't think of a reason for why we'd turn on PCRE2_UTF when matching byte-for-byte like that.
