Angle brackets not parsed correctly

When autolinking strings with angle brackets not belonging to html tags, the bracketed section is stripped out. For example, when passing in **http://gs.3g.cn/D/b3964/w<gof=N53fa>** the output is **http://gs.3g.cn/D/b39664/w**.

Is there any way to prevent this so that the bracketed region is included in the link?
