DBCS character-strings are constructed using characters from the Double-Byte Character Set. DBCS character-strings can be embedded into nonnumeric strings, including mixed literals. Embedded DBCS character-strings must be delimited by an opening "shift-out" control character and a closing "shift-in" control character. DBCS literals may include characters that range from X'00' to X'FE' for both bytes. DBCS literals cannot include X'0F7F' (or X'0F7D' if the APOST option is selected).
