User:Evad37/showhardspaces

showhardspaces is a script that makes hard spaces, a.k.a. non-breaking spaces (&amp;nbsp;) visible. They will be shown as " • ", so that you can check if they have been applied correctly per Manual of Style.

WARNING: I have only tested this code on Chrome (v32) on Windows 7 – use at your own risk.

Installation
To install the script, add: importScript('User:Evad37/showhardspaces.js'); // User:Evad37/showhardspaces to Special:MyPage/common.js. There will be a link "Highlight hard spaces" in the toolbox on the left on every mainspace article.
