Runtime Character Set

Each EBCDIC CCSID consists of two character types: invariant characters and variant characters.

The following table identifies the hexadecimal representation of the invariant characters in the C character set.

Note:

Not all EBCDIC character sets have all invariant characters at the invariant code points. Here are the exceptions:

Code page 290, used in Japanese CCSIDs 290, 930, and 5026, has the lowercase Latin characters a-z in a nonstandard position.
Code page 420, used in some Arabic CCSIDs, does not have the back quotation mark (`) whose hexadecimal value is 0x7a.
Code page 423, used in some older Greek CCSIDs, does not have the ampersand (&) whose hexadecimal value is 0x50.
Code pages 905 and 1026, both used in some Turkish CCSIDs, have a hexadecimal value of 0xfc for the double quotation mark instead of the invariant hexadecimal value of 0x7f.

The following table identifies the hexadecimal representation of the variant characters in the C character set for the most commonly used CCSIDs.
