In all but Shift-JIS encoding, code points are represented in the font file as a 16-bit Unicode code point. In Shift-JIS encoding, when the code point is represented with a single byte, the stored code unit is this byte, zero-extended to 16 bits. For a 2-byte encoding, the high 8 bits are the first byte in the sequence, and the low 8 bits are the second byte. |
