Its done... https://subosito.com/posts/imagemagick/ but I guess its not the usual case. > If I am right then it is better to introduce binaryStdout and binaryStdin > messages.

StdioRef stdout writeStreamDo: [ :stream | stream nextPutAll: 'a ≠ b' ]. StdioRef stdout writeStreamEncoded: 'cp-1250' do: [ :stream | stream nextPutAll: 'Příliš žluťoučký kůň úpěl ďábelské ódy.' ]. StdioRef stdout binaryWriteStreamDo: [ :stream | stream nextPutAll: #[1 2 3] ]. cheers -ben
