I am surely dumb, but whatever and how many '\' are used
the '+' is always returned as a ' ' in the reply.

So the specific example will be appreciated,
as a single quoting usually works in regexes

  $ cd /etc/setup
  $ zcat gcc-g++.lst.gz |grep -P "g\+\+"
usr/bin/g++.exe
usr/bin/i686-pc-cygwin-g++.exe
usr/share/man/man1/g++.1.gz

Is something "sanitizing" the query on server side to avoid
nasty surprise ?

  $ zcat gcc-g++.lst.gz |grep  -P "g++" |wc -l
723
