Currently Firefox browsers replace non-breaking spaces with normal spaces when
editing page. There should be a workaround on MediaWiki side: all Unicode U+00A0
spaces in article code should be replaced with another symbol (something like
U+20DE) before sending edit form to browser. When saving code, U+20DE should
become U+00A0.
Such a behavior should be enabled:
- for Firefox users by default
- for other users who enabled this option in their user settings
Also, that's good to replate with U+20DE too.
