How can I add Author/Title/Creator/Keywords/... to PDF documents,

Try:
\setupinteraction
[state=start,
title={...},
author={...},
keyword={...}]
Adobe seems to have some strange way of encoding those strings: I can
use scaron in those fields (if I write something manually in
Acrobat), but then the whole string becomes two-byte with some prefix
and resembles unicode encoding.
For example, to get the Hàn Thế Thành's name in the Author's field of
the PDF manual properly, one should probably write something like
/Author(feff 0048 00e0 006e 0054 0068 1ebf 0054 0068 00e0 006e 0068),
without the spaces and with characters instead of the corresponding
hex-code. (Note: If someone writes ConTeXt support for it, be careful
about escaping parenthesis for U+29xx - not that anyone would need
those arrows in comments, but you never know.)
feff ("byte order mark", whatever that means) at the beginning seems
to be only a switch for multi byte encoding inside the parenthesis.
I didn't try this out yet, so perhaps I'm missing something else here
as well. If anyone knows how to try it out, please report if it works.
I guess that another encoding, similar to enco-pdf should be defined
first and then used inside the \doPDFsetupidentity definition. If
characters other than those present in one-byte pdf encoding are
present in an argument (Author, Comment, ...), than this more advanced
encoding should be used for that field.
\PDFunicodetrue
should do the trick (i need to look into the bookmarks since pdftex
needed a fix for that)
Out of curiosity: can you manually write Vietnamese characters to
those fields in Adobe? I have a feeling that they loose the second
accent if I copy-paste some double-accented characters, but I don't
know if this is just a visual effect/lack of proper fonts or if it
really isn't supported.
in principle, it should be possible; the problem with cut and paste is that the operating system may do things with the buffer
