Mozilla is unable to execute a script called inside an anchor if there is a non ascii-character escaped in th href property. This might be related to bug 40469. I'm appending a testcase. <a href="javascript:confirm('mOziLLa ?');">question 1</a><br> No non-ascii character in href, the script works as intented and popup a message dialog. <a href="javascript:confirm('mÖzïLLà ?');">question 2</a><br> Non-ascii characters in href, the whole property is escaped into "<code>javascript:confirm(%27m%D6z%EFLL%E0%20?%27);</code>", the javascript interpreter reports a syntax error. Fix suggestion : do not escape href when starting by "javascript:"
