In addition to replacing the @s (@) in email addresses in order to avoid spambots, you can also replace any other character with its corresponding ASCII code. The table on the right represents most the characters and their corresponding ASCII character codes that are likely to appear in your email addresses. It is possible to completely disguise an email address with nothing but ASCII codes. For example, the following email address will appear exactly the same to a visitor using a browser:
Color coded to the ASCII character codes that correspond to the actual characters in the address.
You may also use ASCII character codes to create a munged but clickable link to an email address from your website. It is advisable to also mung the "mailto:" in the <a> tag as some spambots may use this as a way of identifying email addresses on a page.
(Where you replace both XXX and YYY with your munged address.)
