Since raw[4:5] does not match those, it's an invalid UTF-8 byte sequence. So, technically this does not happen...

...ethod as in UTF-8 to store variable length integers: - read one byte B0 from the stream - if B0 = 0xxxxxxx then the read value is B0 -> end - if B0 = 10xxxxxx, the encoding is invalid - if B0 = 11xxxxxx, set L to the number of leading binary 1s minus 1: B0 = 110xxxxx -> L = 1 B0 = 1110xxxx -> L = 2 B0 = 11110xxx -> L = 3 B0 = 111110xx -> L = 4 B0 = 1111110x -> L = 5 B0 = 11111110 -> L = 6 - assign the bits following the encoding (the x bits in the examples) to a variable R with a magnitude of at least 56 bits - loop from 1 to L - left shift R...

I'm implementing a FLAC decoder from scratch (save OGG stuff if I can help it) because libFLAC simply will not fit my embedded platform, For the most part I'm implementing using just the documentation but not all of the documentation is concise (especially about variable sized fields) and after looking at the libFLAC source I find myself befuddled so I thought it best to get the
