IBM PC code sets

IBM® PC code sets are the code sets originally supported on the IBM PC systems and AIX®. The IBM PC code sets assign graphic characters to the Control One (C1) control area. Applications that depend on these control characters cannot support these code sets.

The ASCII characters are encoded with the most significant bit (MSB) zero in positions 0x20-0x7e. The extended Latin 1, combined with the IBM PC unique character sets, make up the extended set of characters which are encoded in positions 0x80-0xfe. The following table shows the location of the control, ASCII, and extended characters for the IBM-850 code set.

Character Encoding	Code Point	Description	Count
000xxxxx	00–1F	Controls	32
00100000	20	Space	1
0xxxxxxx	21–7E	7-bit	94
01111111	7F	Delete	1
1xxxxxxx	80–FE	8-bit	17
11111111	FF	All ones	1

The IBM PC unique character set includes the following:
