Hi Sahasra,

Thanks for ur wishes and wish u the same......

In the past, SAP developers used various codes to encode characters of different alphabets, for example, ASCII, EBCDI, or double-byte code pages.

ASCII (American Standard Code for Information Interchange) encodes each character using 1 byte = 8 bit. This makes it possible to represent a maximum of 28 = 256 characters to which the combinations [00000000, 11111111] are assigned. Common code pages are, for example, ISO88591 for West European or ISO88595 for Cyrillic fonts.

EBCDI (Extended Binary Coded Decimal Interchange) also uses 1 byte to encode each character, which again makes it possible to represent 256 characters. EBCDIC 0697/0500 is an old IBM format that is used on AS/400 machines for West European fonts, for example.

Double-byte code pages require 1 or 2 bytes for each character. This allows you to form 216 = 65536 combinations where usually only 10,000 - 15,000 characters are used. Double-byte code pages are, for example, SJIS for Japanese and BIG5 for traditional Chinese.

Using these character sets, you can account for each language relevant to the SAP System. However, problems occur if you want to merge texts from different incompatible character sets in a central system. Equally, exchanging data between systems with incompatible character sets can result in unprecedented situations.

One solution to this problem is to use a code comprising all characters used on earth. This code is called Unicode (ISO/IEC 10646) and consists of at least 16 bit = 2 bytes, alternatively of 32 bit = 4 bytes per character. Although the conversion effort for the R/3 kernel and applications is considerable, the migration to Unicode provides great benefits in the long run.

The below link provides the Unicode glossory which help u out.

Thankyou,

sahara,

Unicode is an international standard that assigns characters from virtually every language and script a unique Unicode Scalar Value, which is a number written in hexadecimal notation. As a notational convention "U" is prefixed to the Scalar Value. For example, the character A has the Unicode Scalar Value U0041, Ä is U00C4, and 가 is UAC00. In addition, every character has a unique character name (although the CJK ideographs do not always have a character name listed).
