+      represents the same sequence of characters as the first string,
+      ignoring the case.
+      Character values between 65 and 90 (ASCII A-Z) are interpreted as
+      values between 97 and 122 (ASCII a-z).
+      Since this method is optimized for performance, the ASCII character
+      values are not converted in any way. The caller has to make sure that
+      all ASCII characters are in the allowed range between 0 and
+      127. The ASCII string must be greater or equal in length as asciiStrLength.
+      This function can't be used for language specific comparison.
