Type a non-breaking space, no not the  

A little trick I learned recently was to insert non-breaking spaces into text documents using the UTF-8 non-breaking space character. You can enter this on a UTF-8 capable keyboard using the codeĀ U+A0, or you can enter it on a Mac by typing the keyboard combinationĀ Shift+Opt+Space:
