[gnome-desktop: 3/6] tests: Test correct space vs. em-space handling

[Matthias Clasen <matthiasc src gnome org>]

commit 0599decdfdec877822c721114f892e35cd799c4f
Author: Florian Müllner <fmuellner gnome org>

    tests: Test correct space vs. em-space handling
    
    This is analogous to the existing colon vs. ratio test which checks
    that:
    
     - UTF8 locales use the UTF8 character
       (in both LTR and RTL locales)
    
     - non-UTF8 locales use an appropriate
       ASCII replacement
