区位码、国标码和机内码有什么区别？Zone-position vs GB code vs internal code?
区位码是「区号 + 位号」的十进制编号（如「啊」为 1601）；国标码是区号和位号各加 0x20（3021）；机内码（即 GB2312/EUC-CN 文件里实际存储的字节）是各加 0xA0（B0A1）。The zone-position code is the decimal zone + position (啊 is 1601); the GB code adds 0x20 to each (3021); the internal code — the bytes actually stored in GB2312/EUC-CN files — adds 0xA0 (B0A1).
