#### 30.5.3 Avoiding use of special characters in URIs

URI (Uniform Resource Identifier) encoding rules are different from HTML and XML encoding rules. There is no way to URI-encode characters that have a decimal value greater than 255; you get only eight bits for each character. DITA2Go does not know that a particular attribute value or text string is intended to become part of a URI, and by default converts any characters outside this range to numeric entities. Therefore, avoid special characters such as trademarks and registration marks in any Internet or email addresses in your document.
