> If a string contains control characters in the regions matched
> by wild card characters then in some situations a LIKE will
> return false instead of true and the row will not be returned.
> Caused by the dynamic like optimization using >= with a prefix
> which is is equivalent to >= on the prefeix appended with
> blanks and not null (\u0000) characters.
