TYPO3 Core

typo3/template.php contains the following code

/**
 * Deprecated fontwrap function. Is just transparent now.
 *
 * @param    string        Input string
 * @return    string        Output string (in the old days this was wrapped in <font> tags)
 * @deprecated since TYPO3 3.6
 */
function fw($str)    {
    return $str;
}

Log each call to the deprecation log that we can remove this in 4.6
