geany has setting in Edit > Preferences > Editor > Display > Show white space. I think it should be default. It shows one pixel mark for regular white space, which is hard to see, though. It shows just space for non breaking space. Inverting colors helps a bit.

Status in Geany: New Status in gedit: New Status in GNOME Terminal: New Status in nano: New Status in xfce4-terminal: New Status in xorg package in Ubuntu: Invalid Bug description: OS: from Hardy to at least Trusty. When you use Finnish keyboard, you have to hold Alt Gr down to type | or \ or certain other characters. When typing a shell command, you may often want to enter a space character after such characters. But it easily happens that Alt Gr is still down when you press space, and consequently you type non-breaking space character U+00A0 (at least, if you use UTF-8 keyboard layout, which is default in Ubuntu). $cd /tmp ; echo 0 > foo\ bar ; ls "foo bar" ls: cannot access foo bar: No such file or directory $cat foo bar | grep 0 No command ' grep' found, but there are 16 similar ones grep: command not found Besides it may be hard to see the typing error, as non-breaking space character looks exactly same as regular space character. A way to avoid such typos would be to use another keyboard shortcut for non-breaking space. Besides non-breaking space should look different than regular space in terminal emulators and in editors. A workaround in to run setxkbmap -option "nbsp:none" to make <Alt Gr><space> type regular space character, and use `printf '\u00a0'` or `printf "\xc2\xa0"` to have a non-breaking space in scripts and in command line. Non-breaking space can be typed (in GTK apps) by <Ctrl><Shift>u 00a0<Enter>, if needed, but it looks exactly like a regular space. For me, <Super><Space> would be a good shortcut for non-breaking space.
