[tex-live] bug in attachfile.sty

Hello,
I haven't heard from Scott Pakin about this bug, so I am forwarding to a
wider audience in hope that someone knows how to correctly set mimetype in
\attachfile (i.e. /Subtype value of /EmbeddedFile attachment).
More generically, how would one propagate a TeX string containing slash
"/" into a PDF string? Trying to do something like this:
\pdfstringdef{\textp}{text\#2Fplain}
ends up with the value /text\0432Fplain in the PDF file which is not what
we want.
Also, the reason I am emailing tex-live is because TeX Live includes
attachfile package and the email below contains a simple bugfix (/Subtype
is a name and not a string according to the PDF spec).
Kind regards
Tigran

Hello Scott,
I am using your attachfile package and am very happy with it.
However, there is a small glitch in the way it handles the 'mimetypes' setup
option. For example, if I write:
attachfilesetup{%
description={Tiqwah source code},%
mimetype={text/plain},%
print={false},%
author={Tigran Aivazian},%
timezone={Z}% Z means GMT.
}
The resulting PDF file contains the following object:
7 0 obj <<
/Type /EmbeddedFile /Subtype (text/plain)
/Length 35
/Filter /FlateDecode
>>
i.e. it handles /Subtype as a string. But the PDF spec says it is a name, and
looking at a PDF file with attachment created by Adobe Acrobat I see /Subtype
values like this:
/Subtype /application#2Foctet-stream
Now, if I modify your package as follows:
@@ -245,7 +245,7 @@
\def\atfi at mimetype{}
\define at key{AtFi}{mimetype}{%
\atfi at pdfstringdef\atfi at mimetype{#1}%
- \edef\atfi at mimetype{/Subtype (\atfi at mimetype)}%
+ \edef\atfi at mimetype{/Subtype /\atfi at mimetype}%
}
\define at key{AtFi}{icon}{%
\def\atfi at icon{/Name /#1}%
then the mimetypes value will be stored as a name, but it is very difficult to
set the value '/' in there.
I tried mimetypes=text\#2Fplain, but I end up with
/Subtype /text\0432Fplain which is wrong.
Can you please tell me how to set the slash in "text/plain" correctly?
And is the above fix to attachfile.sty correct or do you have a proper fix?
Kind regards
Tigran
