Moe uses ISO-8859-15 instead of UTF-8 because an 8-bit character set (combined with romanization if needed) can convey meaning safely and more efficiently than UTF-8 can.
UTF-8 is a great tool for tasks like writing books of mathematics or mixing Greek with Chinese in the same document. But for many other everyday computing and communication tasks, an 8-bit code like ISO-8859-15 is much more practical, efficient and reliable. There is no such thing as an "invalid" or "out of range" ISO-8859-15 character.
