Details

Browser Blacklist for unicode non compliant browsers. Contains a list of regexps: "/regexp/" matching problematic browsers. If the user-agent of a browser matches one such regex, the "safemode" field is used when editing (see the safemode item in Manual:Parameters to index.php for details).

Default values

MediaWiki versions:

1.30 – 1.31

In MediaWiki 1.30 , a feature test is used to check whether browsers can correctly round-trip Unicode characters:

$wgBrowserBlackList = [];

MediaWiki versions:

1.11 – 1.29

$wgBrowserBlackList = array(
    /**
     * Netscape 2-4 detection
     * The minor version may contain strings such as "Gold" or "SGoldC-SGI"
     * Lots of non-netscape user agents have "compatible", so it's useful to check for that with a negative assertion. The [UIN] identifier specifies the level of security in a Netscape/Mozilla browser, checking for it rules out a number of fakers.
     * The language string is unreliable, it is missing on NS4 Mac.
