Obfuscating mailto field

If you would like to post your e-mail address on the web page and you want to prevent spam bots from harvesting your address someone figured out a clever way to obfuscate the e-mail address using HTML codes instead of characters ie. m&#97i instead of a. For example address vuksan@veus.hr converts into

<a href='m&#97i&#108&#116&#111:%76%75%6b%73%61%6e%40v%65%75s%2e%68r'>v&#117&#107&#115&#97&#110@&#118&#101&#117&#115.hr</a>

This is not a bulletproof solution. Eventually spamers will figure it out but for right now this may slow them down a little bit. Since I started using it  I haven't seen a spam e-mail :-).

The script was originally at

I didn't like parts of the script so I modified it. Final result is following
