This is OK on ASCII-based platforms or using an ASCII-compiled libcurl.

On a non-ASCII (i.e.: EBCDIC) host with conversions, hexadecimal escapes
(%xx) are translated to the corresponding ASCII characters, instead of
the equivalent character in the host character set.

... So this use is not portable !
