-   We convert the input string to Unicode.

-   The standardized Unicode encodings are UTF-8, UCS-2, UCS-4, UTF-16,
-   UTF-16BE, UTF-16LE, UTF-7.  UCS-2 supports only characters up to
-   \U0000FFFF.  UTF-16 and variants support only characters up to
-   \U0010FFFF.  UTF-7 is way too complex and not supported by glibc-2.1.
-   UCS-4 specification leaves doubts about endianness and byte order mark.
-   glibc currently interprets it as big endian without byte order mark,
-   but this is not backed by an RFC.  So we use UTF-8. It supports
-   characters up to \U7FFFFFFF and is unambiguously defined.  */
