On http://eo.wikipedia.org a javascript error is thrown:
"JavaScript parse error: Parse error: Illegal token in file 'MediaWiki:Common.js' on line 669", although the mentioned page contains perfectly valid js.
Since r91608, jsmin+ is used to validate js pages, which seems to be too strict about identifiers that contain non-ascii-chars.
As a workaround $wgResourceLoaderValidateJS can be disabled by default until this is resolved.
