[Bug 1612000] Re: Samba client/server cannot manage special characters

[James]

I am happy to help.  Should I test with a different distribution or (if
you can give me instructions to do so) should I test on Ubuntu with a
different version of Samba?

Title:
  Samba client/server cannot manage special characters

Status in samba package in Ubuntu:
  New

Bug description:
  A little background... I have a media server running Ubu 10.04 with a
  media share containing FLAC files in a pretty standard hierarchy.
  This server (in service since 2010) has been accessed by machines
  running from 10.04 to 14.04 without any issues.

  I have recently built/upgraded two client machines to from 14.04 to
  16.04 and these machines are having trouble with that Samba-served
  share.  If a file or folder contains a question mark, that file or
  folder will not be accessible--though it will appear in Nautilus and
  in the Terminal.

  In the case of a file (say 01 - Who Are You?.flac) if you double-click
  the file (or otherwise launch it) you will get a file not found error;
  this is true in the Terminal as well (using, say, ffplay).  In the
  case of a folder it will appear to be empty and if you double-click
  the folder you will get a folder not found error.  In either case, the
  question mark is clearly shown in both Nautilus and bash.

  If I create a share on one of my Ubu 16.04 machines (with similar
  parameters) those files and folders which contain question marks do
  not appear on client machines (regardless of version) when that share
  is mounted.  Interestingly, these 16.04 servers are also not able to
  share files or folders which contain colons.

  This is all with mangled file names disabled.  If I enable it, I get
  mangled file names which share as expected.

  (Other characters may be effected, but these are the only two I have
  tested.)

  In short, files and folders containing question marks and colons
  should appear in shares and be launchable.  With 16.04 this is not the
  case.

  From the 10.04 machine:

  samba:
    Installed: 2:3.4.7~dfsg-1ubuntu3.15
    Candidate: 2:3.4.7~dfsg-1ubuntu3.15
    Version table:

  From the 16.04 machine:

  samba:
    Installed: 2:4.3.9+dfsg-0ubuntu0.16.04.2
    Candidate: 2:4.3.9+dfsg-0ubuntu0.16.04.2

  I am happy to provide additional details or tests as requested.
