Hi!

Firebird has two "default" UDF : ib_udf and fbudf.

Currently we're useing WIN1250/PXW_HUNDC. The DDL is the next :

DECLARE EXTERNAL FUNCTION SUBSTR
CSTRING(32767),
SMALLINT,
SMALLINT
RETURNS CSTRING(32767) FREE_IT
ENTRY_POINT 'IB_UDF_substr' MODULE_NAME 'ib_udf';

Does ib_udf and fbudf support UTF-8? If so, how to define?
Should we change it?
