Certain rich text editors such as Microsoft Word include the title of the document in the generated RTF. If you do not provide a document title then the title may be automatically generated by using the first few characters of the document. If the first few characters of your document is a replacement string then this will be used as the document title and will possibly render the template unusable. If you are designing an RTF template then always ensure that you specify a sensible document title. You can usually locate the document title field by selecting Properties from the File menu of your RTF word processor.
