Short story about swapping bodies as a job; the person who hires the main character misuses his body. Hence, is the 8-bit version of the two-byte UTF-8 sequence for (0xC3 and 0xB9). Otherwise, an error is raised when decode is supplied invalid base64 data including when trailing padding is incorrect. Adding a varbinary value into an XML type stores it as base64 encoded, and extracting the value the systems already knows how to decode it: Base64 is an encoding algorithm that allows you to transform any characters into an alphabet which consists of Latin letters, digits, plus, and slash.
