javascript - Encoding of window.location.hash

Question

Does window.location.hash contain the encoded or decoded representation of the url part?

When I open the same url (http://localhost/something/#%C3%BC where %C3%BCtranslates to ü) in Firefox 3.5 and Internet Explorer 8, I get different values for document.location.hash:

• IE8: #%C3%BC
• FF3.5: #ü

Is there a way to get one variant in both browsers?

Unfortunately, this is a bug in Firefox as it decodes location.hash an extra time when it is accessed. For example, try this in Firefox:

location.hash = "#%30";
location.hash === "#0"; // This is wrong, it should be "#%30"

The only cross-browser solution is to just use (location.href.split("#")[1] || "") instead for getting the hash. Setting the hash using location.hash seems to work correctly for all browsers that support location.hash though.
