             Bug #: 40660
           Summary: ResourceLoader breaks " " in Javascript literals
           Product: MediaWiki
           Version: 1.20-git
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: Unprioritized
         Component: ResourceLoader
        AssignedTo: [email protected]
        ReportedBy: [email protected]
                CC: [email protected], [email protected],

    Classification: Unclassified
   Mobile Platform: ---


If a Javascript file loaded through ResourceLoader contains the text strings
" ", " ", or " ", these will be changed to a raw space or
non-breaking space. This causes a problem in
[[en:MediaWiki:Gadget-charinsert.js]], as that gadget wants to effectively do
document.createTextNode(' ') to include the literal string " " in the
charinsert box.

The source of the replacement is in includes/cache/MessageCache.php, at the end
of get(). Since that's in such a low-level function, I don't know what the
consequences of changing it might be for other messages. Another possibility
might be to have ResourceLoader use getMsgFromNamespace instead to avoid the
problematic replacement.
