UTF-EBCDIC is a character encoding used to represent Unicode characters. It is meant to be EBCDIC-friendly, so that legacy EBCDIC applications on mainframes may process the characters without much difficulty. Its advantages for existing EBCDIC-based systems are similar to UTF-8's advantages for existing ASCII-based systems. Details on UTF-EBCDIC are defined in Unicode Technical Report #16. To produce the UTF-EBCDIC encoded version of a series of Unicode code points, an encoding based on UTF-8 (known in the specification as UTF-8-Mod) is applied first. The main difference between this encoding and UTF-8 is that it allows unicode code points U+0080 through U+009F (the C1 control codes) to be represented as a single byte and therefore later mapped to corresponding EBCDIC control codes. In order to achieve this 101XXXXX was used instead of 10XXXXXX as the format for later bytes in a multi-byte sequence. As this can only hold 5 bits rather than 6, UTF-EBCDIC will generally produce larger output for the same input data than UTF-8. This transformation leaves the data in an ASCII based format, so a reversible byte-byte transform is made on this data using a lookup table to make it as close to normal EBCDIC code pages as feasible. These steps can be easily reversed to recover the unicode code points. Generally, this encoding form is rarely used, even on EBCDIC based mainframes for which it was designed. IBM EBCDIC based mainframe operating systems, like z/OS, usually use UTF-16 for complete Unicode support. For example, DB2 UDB, COBOL, PL/I, Java and the IBM XML toolkit support UTF-16 on IBM mainframes. Codepage layout

There are 160 characters with single-byte encodings in UTF-EBCDIC (compared to 128 in UTF-8). As you can see, the single byte portion is similar to IBM-1047 instead of IBM-37 due to the location of the square brackets. CCSID 37 has [] at hex BA and BB instead of at hex AD and BD respectively.

White cells containing a large single-digit number are the start bytes for a sequence of that many bytes. The unbolded hexadecimal code point number shown in the cell is the lowest character value encoded using that start byte (this value can be greater than the value which would be obtained by following the start byte with continuation bytes which are all 65 (hex 0x41), if this would result in an invalid overlong form). Reduced payload of a continuation byte (5 bits, compared to 6 bits in UTF-8) results in different ranges of code points represented by code sequences of the same length. Orange cells with one dot are continuation bytes. The hexadecimal number shown after a "+" plus sign is the value of the 5 bits they add.
