Thread:VisualEditor/Feedback/Special character list...edits do not appear

Web browser: Firefox 36.0.1 Operating system: Windows 7 Wiki skin: Monobook

I edited the special character list at https://nv.wikipedia.org/wiki/MediaWiki:Visualeditor-specialcharinspector-characterlist-insert When I try to edit an article, my edit to the list does not appear. I went to http://jsonlint.com/ to validate the code, and it says:
 * Parse error on line 1:
 * <!DOCTYPEhtml><htmll, suddenly all the symbols and characters in the list changed to Unicode points (like "\u2212": "\u2212"). I don't know how that happened and I can't seem to revert it.
