echo text | gpg2 --sign --textmode -a I can create messages with a one pass signature containing a Literal Data packet in TEXT ('t') format.
If I skip the
--textmode option it will generate BINARY ('b') mode.
However according to RFC 4880 Sec 5.9 there is also a 'u' mode, which is basically text mode in UTF-8. Is there a way to generate this with GnuPG command line? (
--charset=UTF8 had no effect when piping in a UTF-8 test file with gpg4win-vanilla-2.3.0 containing gpg2 2.0.29).
