Insert Formating Marks Non-breaking Space is working from the menue line but using the key codes Ctrl+Shift+Space did nothing on my xubuntu box, and on a friends Windows 7 (libreOffice Version 4.?) system.
I have to correct me, the key code seems to work on windows (lo 4.4 & 5.0.2.2) but the protected-blanc is not longer marked in view non-printing character mode. on linux, the key is still not working, but inserting via menue resulted in an marked blank. a) the key code should work b) the non-breaking blanc should be marked in non-printing character mode.

I found a duplicate (see my comment), so from my point of view it is confirmed? But I have no Linux and can therefore not confirm it myself.

i installed the newest xubuntu 15(?) and the new libreoffice 5.0.22 has both menu and keyboard non-breaking space working fine....
