[encode_decimalhtml]

Description

Internet Explorer doesn't support certain HTML equivalents used by the built-in [encode_html] (such as ™ for ™). This custom tag instead uses decimal equivalents for the encoding (so, ™ becomes ™), which seems to be more compatible. It also strips out the non-printing character codes 0-8 which will also render incorrectly in IE otherwise.

Sample Usage

encode_decimalhtml($myText);
