[Bug 1990755] Re: HYPHEN character escaped in filenames with BACKSLASH

[Bernhard Riegler]

Hi Nick,

I disagree with this filesystem name space pollution.

UNIX has a SPACE as parameter separator.
UNIX has a SLASH as filesystem directory separator
DOS  has a BACKSLASH as filesystem directory separator

nowadays are directory_names and file_names with SPACES, causing problems
with CLI shell-scripts and BACKUP programs.

adding escaping into filesystem name space is causing more problems.

I have already shell scripts replacing SPACE with UNDERSCORE
and reporting BACKSPACE in filesystem namespace to keep my filesystems pure and clean.
I also monitor UNICODE symbols in filesystem name space.

  HYPHEN is normal ASCII character or escaped by "\x2d"
  HYPHEN needs no escape , but the BACKSLASH is making troubles.
  no BACKSLASH allowed in filenames and directory names.
  seems to be a bad habit of "systemd" and "snap"
