            Bug ID: 230068
           Summary: ps: processes with non-ASCII characters are hidden
                    from list in "ps auxww"
           Product: Base System
           Version: 11.0-RELEASE
          Hardware: amd64
                OS: Any

File contains example scripts and output from test-run.

A process with non-ASCII character in its name does not show up in the listing
by 'ps auxww' (or other variants).
At best, it confuses the one who started the process.
At worst, unauthorized processes can act on a system without showing up in the
process list.

For example, start a processes named 'GuterProzess' and 'BöserProzess'.
In ps only 'GuterProzess' will appear.
(BTW, e.g. lsof lists the other process too.)
