Bug description:
OS: from Hardy to at least Bionic.
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
$cat foo bar | grep 0
No command ' grep' found, but there are 16 similar ones
grep: command not found
Besides it may be hard to see the typing error, as non-breaking space
character looks exactly same as regular space character.
A way to avoid such typos would be to use another keyboard shortcut
for non-breaking space. Besides non-breaking space should look
different than regular space in terminal emulators and in editors.
WORKAROUNDS:
Run
setxkbmap -option "nbsp:none"
to make <Alt Gr><space> type regular space character.
Even better option is to use "classic", "mac" or "nodeadkeys" keyboard
variant instead of "". This could be set up in /etc/default/keyboard
and maybe in configuration dialog in your desktop environment.
Non-breaking space can still be typed (in GTK apps) by <Ctrl><Shift>u
00a0<Enter>, if needed. Another option is to use compose key:
<compose> <space> <space>.
In Bash scripts you could also use `printf '\u00a0'` or `printf
'\xc2\xa0'` to print a non-breaking space. (You could use `echo -en`
instead of `printf`.) Or you could set up a variable `readonly
nbsp=$'\u00a0'`.
