All Japanese client character set must be manually enabled for use in Teradata Database, as shown in Chapter 3: “Using Standard Teradata Client Character Sets.”
Japanese characters tend to be drawn to fill a square, and text is often written vertically. Standard fixed-width Western writing tends to require two characters to fill a square, and the style is called Hankaku, or half-square, as opposed to the standard Zenkaku, or full-square, mode of writing.
SQL keywords, such as SELECT, cannot be translated into Japanese and be expected to act as keywords. Only Hankaku Romaji characters may be used to type a keyword, not Zenkaku Romaji characters.
