Special Characters to Escape

Special characters must be escaped only if they have special meaning in the context in which they are being used. For example, the asterisk (*) is a special character only in the "Include" and "Exclude" attributes of an item definition, or in a call to CreateItem. In all other cases, the asterisk is treated as a literal asterisk. While you do not need to escape asterisks everywhere in project files, doing so does no harm.

Use the notation %xx in place of the special character, where xx represents the hexadecimal value of the ASCII character. For example, to use an asterisk (*) as a literal character, use the value %2A.
