Anti Spam Bot Email by ASCII

This class can be used to encode e-mail addresses to avoid robots that crawl pages to harvest e-mail addresses. It takes an e-mail address and can generate two versions: one for displaying in Web pages and another to use in mailto: links. In both versions the @ character is replaced by alternative characters. In the mailto: link version the other characters are encoded using equivalent numeric HTML entities.
