While working on a conversion project, I noticed that certain files would throw KeyError's for \N{...} strings.
A minimal test case looks like:
world = "world"
print("hello {} \N{snowman}".format(world))Which I would expect to be left alone or rewritten as:
world = "world"
print(f"hello {world} \N{snowman}")I had trouble reproducing it in pytests. This seemed to trigger the same error:
