ABAP Keyword Documentation → ABAP Glossary →Character Representation
Binary coding of characters. To assign a character set to a character representation, you use codepages. The ISO-8859 codepages are single-byte character representations, in which every character is encoded in up to one byte. SJIS and BIG5 are double-byte character representations for Japanese and traditional Chinese fonts. The Unicode character representations enclose all characters world-wide and can be encoded by one, two, or four bytes, depending on the UTF representation.
