Hans,
sorry for insisting in this issue. Here is the sample:
\setupinteraction[state=start]
\setupinteractionscreen[option=attachment]
\setuppapersize[A5, landscape]
\setuppagenumbering[location=]
\starttext
\startbuffer[abc]
hola μαριόλα
\stopbuffer
This PDF document contains a visible
attachment.\attachment[name=hidden.txt, title={χαλεπὰ τὰ καλά},
author=ConTeXt, subtitle=χαλεπὰ τὰ καλά, method=hidden, buffer=abc]
This PDF document should contain the same hidden attachment (under
a different name\attachment[name=visible.txt, title={χαλεπὰ τὰ
καλά}, author=ConTeXt, subtitle=χαλεπὰ τὰ καλά, method=visible,
buffer=abc].
\stoptext
I attach the patch. With the previous sample, it is clear that the
buffer keyword is needed in method=hidden.
Many thanks for your help,
Pablo
