Problems with field names containing special chars (such as plus sign)
I have (OpenFOAM) simulations with field names containing plus signs (these are mass fractions of ions) which I visualize in ParaView.
As it appears, Paraview does not always handle those correctly. For example if have field "A" selected, and then switch to field "A+", is still shows "A" in the legend (and the other way around). Also these fields are not everywhere possible to select.
