Now hyperref 6.79p only supports option `unicode' or
`pdfencoding' with values 'unicode' or `auto'. In the latter
case PDFDocEncoding is only used, if the string is an ascii string
(7-bit characters).

No idea, how to get rid of the warning
"Failed to convert input string to UTF16...".
The strings are already in UTF16, thus an additional conversion
have to fail.

The source code seems to suggest, a two byte BOM marker
skips the conversion test, but neither ^^fe^^ff, ^^^^feff,
\376\377 work.
