Well, probably not voodoo but very strange to me. Try this: echo "\\\f[U-S]\[uF8E8]\f" | groff -Tpdf | pdftotext - - And if you see the same as me, you'll see a white circle with an intersection symbol in it.
Now, try instead and send the same output to a file: echo "\\\f[U-S]\[uF8E8]\f" | groff -Tpdf >t.pdf Open the file in your preferred pdf-viewer and you should see a circle with an 'R' in it (registered trademark?), i.e. a completely different glyph. pdftotext should not be responsible because groff has already done its job. If you see the same, could you explain this to me - or maybe just slap my face so it points in the right direction ;) Regards, Morten
