It might be simplest to wrap that in `if PY2` (when can we drop python2 support 
again?). I don't believe this can happen with py3 due to the try-catch here 
<https://github.com/llvm/llvm-project/blob/master/llvm/utils/lit/lit/util.py#L82>.

A lot of this stuff could be cleaned up when python2 is gone. Right now it's 
very confusing to reason about what is the type a thing in which python version.

`replace` or `backslashreplace` [[

strategy might be better, so that the presence/value of the erroneous character 
is not completely lost.
