Character Encodings/Code Tables/EBCDIC/EBCDIC 1024

IBM code page 1024 is an EBCDIC code page with full T.61 support used in IBM mainframes. Code page 435 encodes more characters and unifies the underscore with the combining underline.

There are non-spacing diacritic characters. However, code page 1024, as well as T.61, defines a fully specified character repertoire, mapping a list of composition sequences to ISO/IEC 10646 character names. The isolated non-spacing bytes are not included in this repertoire, although spacing variants of the diacritics not otherwise present in ASCII are included, with the ASCII space being the trail byte. Hence, only certain combinations of lead byte and follow byte conform to the ISO/IEC standard.

This system also differs from the Unicode combining character system in that the diacritic code precedes the letter (as opposed to following it).

A little anomaly is that Latin Small Letter G with Cedilla is coded as if it were with an acute accent, that is, with a 0xC2 lead byte, since due to its descender interfering with a cedilla, the lowercase letter is usually with turned comma above.

The underline at 0xAD can be inserted under any letter.

In total 13 diacritical marks can be followed by the selected characters from the primary set:
