   Thanks for filing Andrew!
   
   Here is a reproducer test case:
   
   ```
       test_utf8!(
           ilike_utf8_scalar_regex,
           vec!["%%%"],
           vec![r#"\%_\%"#],
           ilike_utf8,
           vec![true]
       );
   
   ```
   
   the 
   ```... pat.replace("%", ".*") ... ```
   areas might need to consider a leading `\` to know to _not_ make the `.*` replacement
