> [Python] pyarrow can't read/write filenames with special characters

> When writing or reading files to or from paths that have special characters
> in them, (e.g., "#"), pyarrow returns an error:
> {code:python}
> OSError: Passed non-file path...
> {code}
> This is a consequence of the following line:
> https://github.com/apache/arrow/blob/master/python/pyarrow/filesystem.py#L416
> File-paths will be parsed as URIs, which will give strange results for
> filepaths like: "bad # actor.parquet":
> ParseResult(scheme='', netloc='', path='/tmp/bad ', params='', query='',
> fragment='actor.parquet')
> This is trivial to reproduce with the following code which uses the
> `pd.to_parquet` and `pd.read_parquet` interfaces:
> {code:python}
> import pandas as pd
> x = pd.DataFrame({"a": [1,2,3]})
> x.to_parquet("bad # actor.parquet")
> x.read_parquet("bad # actor.parquet")
> {code}
