+Override urllib3's behavior to not convert lower-case percent-encoded characters
+to upper-case during url normalization process.
+
+RFC3986 defines that the lower or upper case percent-encoded hexidecimal characters are equivalent
+and normalizers should convert them to uppercase for consistency [1].
+
+However, some sites may have an incorrect implementation where they provide
+a percent-encoded url that is then compared case-sensitively.[2]
+
+While this is a very rare case, since urllib does not do this normalization step, it
+is best to avoid it in requests too for compatability reasons.
