Duplicates CORE2457

This should be the same problem as described in CORE2457, just that it is still valid for Firebird 2.5 servers

With character set UTF8 and collation UNICODE_CI the following error occurs under special conditions (index and select criteria):

GDS Exception. 335544333. internal Firebird consistency check (Invalid expression for evaluation (303), file: evl.cpp line: 819)

The following simple test case can be used to reproduce the error:

CREATE TABLE TEST (
ID BIGINT NOT NULL,
D DATE,
C VARCHAR(50)
);
ALTER TABLE TEST ADD CONSTRAINT PK_TEST PRIMARY KEY (ID);
CREATE INDEX TEST_IDX1 ON TEST (D, C);
SELECT * FROM TEST WHERE (D > '2000-01-01' AND C='test') ORDER BY D, C

We have to stress the fact that UTF-8 is a must for storing international data. And in order to be accepted by the users, a case insensitive collation is required (for indices).
This bug prevents that we can use UTF-8, which we need for storing reservation data in various languages and character sets (for ex. Cyrillic and Latin-1)
