A SQL Anywhere database can use one or two character sets (encodings) for storing character data. The CHAR data types, including CHAR, VARCHAR and LONG VARCHAR, use a single-byte or multibyte character set. UTF-8 may be used. The NCHAR data types, including NCHAR, NVARCHAR and LONG NVARCHAR, use UTF-8.
For more information about the CHAR and NCHAR data types, see Character data types.
