Comment (by daira):

 I tried to post this at https://twistedmatrix.com/trac/ticket/5203 but
 couldn't get past
 the spam filter:

 It doesn't particularly surprise me that this issue has gone for three
 years without
 comments, because the Description is quite rambling and doesn't focus on
 what Zooko wants
 done. (In fact I'm not clear on what Zooko is asking for either.)

 What I would like in order to be able to use `FilePath` in Tahoe-LAFS is
 either:
  * for `FilePath(unicode_path)` to be specified to work, and to return
 Unicode strings
 from methods/attributes that currently return path components;
  * or alternatively, a `UnicodeFilePath` class that works that way.

 Currently I think the status is that `FilePath(unicode_path)` mostly works
 by coincidence
 of the stdlib file APIs accepting Unicode paths, but that doesn't fill me
 with confidence.

 Note that representing paths as byte strings can't possibly work correctly
 in general on
 Windows. It is not sufficient to only be able to represent paths that have
 characters in
 the "ANSI" encoding.

 The behaviour around undecodable paths is a secondary issue that we could
 work around; I
 wouldn't care if we needed wrapper functions to get the behaviour we
 wanted there.
