For the purpose of your needs you have to use htmlEncode function.
They define a number of other useful functions within the object:
HTML2Numerical: Converts HTML entities to their numerical equivalents.
NumericalToHTML: Converts numerical entities to their HTML equivalents.
numEncode: Numerically encodes unicode characters.
htmlDecode: Decodes HTML encoded text to its original state.
htmlEncode: Encodes HTML to either numerical or HTML entities. This is determined by the EncodeType property.
XSSEncode: Encodes the basic characters used in XSS attacks to malform HTML.
correctEncoding: Corrects any double encoded ampersands.
stripUnicode: Removes all unicode characters.
hasEncoded: Returns true if a string contains html encoded entities within it.
