You can use the method used by C (often called "C strings" or "null terminated strings", in which a byte with value 0 signals the end of the string. However, as recently (and vigorously) discussed here, this transfer encoding scheme has the potentially problematic property of prohibiting use of the character at code point 0, NUL. This does not tend to be a problem for most uses, but one should still be aware of it.
Another method is length encoded strings, as used by Java and MFC's CString class, where the length of the string data in bytes is encoded and presented first, and the bytes are handled opaquely.
Either method will do, as there is no TES or data structure explicitly assigned to UTF-8. Use the one best suited for your application. You may want to read UTR 17, "Character Encoding Model", at http://www.unicode.org/reports/tr17/.
