Same thing with less command:

i think the above was a bulk reply and does not apply here, because those settings do not matter here at all. it is more a design question in x (or perhaps rather in your virtual terminal application or your shell or whereever) if it is good to have chars that look exactly the same but behave completely different. like 1 and I and l or O and 0, but just for whitespace (tab vs nl vs space vs nbsp ...) |

The change was made to conform standards. The Finns of you can read the details here:

if the app doesn't show the difference, then it's a bug in the app, not X. |

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. |

Non-breaking space can still be typed (in GTK apps) by <Ctrl><Shift>u 00a0<Enter>, if needed. Another option is to use compose key: <compose> <space> <space>.
In Bash scripts you could also use `printf '\u00a0'` or `printf '\xc2\xa0'` to print a non-breaking space. (You could use `echo -en` instead of `printf`.) Or you could set up a variable `readonly nbsp=$'\u00a0'`. |
