           Summary: support subject strings with invalid UTF-8 sequences
           Product: PCRE
           Version: N/A
          Platform: All
        OS/Version: All
            Status: NEW

PCRE should support subject strings with invalid UTF-8 sequences. Such
sequences should be regarded as non-matching.

This would be useful to grep binary files, such as PDF files, which contain
both text and binary data. The current solution is to call pcre_exec between
invalid UTF-8 sequences, thus many times on such files, and this is very slow.
