I'm searching for a way to represent hymn-style piano introduction marks in Lilypond. I've looked at all the unicode characters I could find, and I haven't found anything appropriate. These are the closest characters I could find: ΓГЃгךדר
But they don't exactly work professionally. I need the opening and closing ones to look exactly the same, and I would like the intersecting bars to be the same length as each other.
