Maybe I misunderstood you I wanted to combine the old filter with the
new reader.

Old filter and old reader are involved via

pandoc Report.tex -t json /home/oub/ALLES/HGs/scripts/stripmath32bit  |
pandoc -f json -t plain -o out.txt

So I tried 
pandoc Report.tex -t json /home/oub/ALLES/HGs/scripts/stripmath32bit

But I got 
pandoc: Cannot decode byte '\xc7': Data.Text.Internal.Encoding.Fusion.streamUtf8: Invalid UTF-8 stream

Now I am even more puzzled.
