UNICODE BE and UNICODE LE Character Sets
Go Up to Character Sets for DOS
InterBase now supports 16-bit UNICODE_BE and UNICODE_LE as server character sets. These character sets cannot be used as client character sets. If your client needs full UNICODE character support, please use UTF8 instead of UNICODE_LE and UNICODE_BE for the client character set (a.k.a LC_CSET). A client can use the UTF8 (or other native) client character set to connect with a UNICODE database.
A database schema is declared to use the new character set in the CREATE DATABASE statement, as follows:
CREATE DATABASE <filespec> <...> DEFAULT CHARACTER SET UNICODE;
Note that InterBase uses “big endian” ordering by default.
The attributes for the UNICODE_BE and UNICODE_LE character sets are shown in InterBase Character Sets.
- Note: InterBase 2008 does not support UNICODE collations in this release. The default collation is binary sort order for UNICODE.
Support for the UTF-8 Character Set
The UTF-8 character set is an alternative coded representation form for all of the characters of the ISO/IEC 10646 standard. To use the UTF-8 character set, you would declare a database schema to use the character set, in the CREATE DATABASE SQL statement, as shown below:
CREATE DATABASE <filespec> <...> DEFAULT CHARACTER SET UTF8;
Additionally, you may use the alias UTF_8.
The attributes for the UTF-8 character set are shown in InterBase Character Sets.
