Question

How can I add spaces between every character or symbol within a UTF-8 document? E.g. 123hello! becomes 1 2 3 h e l l o !.

• I have BASH, OpenOffice.org, and gedit, if any of those can do that.
• I don’t care if it sometimes leaves extra spaces in places (e.g. 2 or 3 spaces in a single place is no problem).

sed(1) can do this:

$ sed -e 's/\(.\)/\1 /g' < /etc/passwd
r o o t : x : 0 : 0 : r o o t : / r o o t : / b i n / b a s h 
d a e m o n : x : 1 : 1 : d a e m o n : / u s r / s b i n : / b i n / s h 

It works well on e.g. UTF-8 encoded Japanese content:

$ file japanese 
japanese: UTF-8 Unicode text
$ sed -e 's/\(.\)/\1 /g' < japanese
