Yes, I transcode them with -scodec dvdsub and that works well. Or did
you mean converting from the bitmaps into text using OCR?

I have been using a teletext decoder with ffmpeg, based on libzvbi, for
many years. Just recently I added an option to generate plain UTF-8
text subtitles rather than bitmaps. My patch from earlier today was a
necessary step to mux this into .mkv and test on my TV. It works :)
Oh well, I'm afraid it might take years to get this merged. :-/
