Yes, creating images for text and mirroring whichever ones you want, then compositing them together, is the obvious method.
Where is the original post? This seems like just an answer. Was this only partially moved?
A question was asked, about drawing text and mirroring some of it (flip or flop), and I answered it.
I guess that answered the question, so the OP deleted it. I wish posters wouldn't do that.
