No; the sequences for codes 128 to 255 begin with 0xC2 and 0xC3 (128-191 and 192-255 respectively). 0xC0 and 0xC1 indicate (illegal) overlong encodings of 0-63 and 64-127 respectively. In general, the two-byte sequences have the (binary) form: 110xxxxx 10xxxxxx The range 0-127 (which must use the single-byte form instead) corresponds to: 1100000x 10xxxxxx Hence, any sequence beginning with 11000000 (0xC0) or 11000001 (0xC1) is illegal. -- Glynn Clements <glynn.clementsat_private>
