ASCII is a character set standard in which each byte represents one character.
The Teradata translation codes for the ASCII client character set are permanently enabled in Database Engine 20.
Various industrial, national, and international organizations have developed custom character sets that are extensions of the ASCII standard. If you use accented and non-Latin characters, do not use the ASCII client character set. Instead, enable use of one of the other supported ASCII-compatible client character sets or a custom (site-defined) character set that exactly matches your character set needs.
Teradata provides following popular extended ASCII-based client character sets, which you must enable before using. Also see Enabling a Client Character Set.
