In sessions where Unicode Pass Through is enabled, truncation of a PTC occurs when the destination buffer does not have 4 bytes to contain the entire surrogate pair. If only 2 bytes remain in a fixed CHAR string, then the string is padded with a SPACE (U+0020) in Teradata mode. In ANSI mode, the truncation mode error is returned.
