The issue is the same as referenced in:

Cannot open .xdmf files in legacy version of fenics + latest Paraview

I wouldnt call it a solution. It was supposed to help debugging the code. Using ascii will slow down the code in parallel. Probably, as it is related to xdmf with h5 encoding, it was adressed at https://bitbucket.org/fenics-project/dolfin/commits/6fbc9fb8e1272c4cdd73d7e2e432dc29ebfe03ac and backport xdmf+boost patch (#169) · conda-forge/fenics-feedstock@3ea2183 · GitHub

which has been fixed in legacy dolfin master branch and on conda.
If you use docker you can use
