My initial tests indicate that for this regex to work as expected,
- libperl5.40 must be installed in the target system but is not part of 
the base system so may not be installed depending on task selection.
- LANG must be set to an installed UTF-8 locale but user-setup-apply 
overrides the default LANG=C.UTF8 with "export LANG=C # avoid locale 
errors from perl".

PS: During my tests I found out that deluser fails with an error about 
File:Find if perl-modules is not installed (not part of the base system 
either).
