ISSUE:       3848
TITLE:       Blob transliteration may not happen inside the union
DESCRIPTION:
JIRA:        CORE-3489
FBTEST:      bugs.core_3489
NOTES:
    [30.10.2024] pzotov
    Bug was fixed for too old FB (3.0 Alpha 1), firebird-driver and/or QA-plugin
    will not able to run on this version in order to reproduce problem.
    Source for this test was taken from ticket almost w/o changes. Only aux view has been added ('v_conn_cset') for
    showing current connection protocol and character set - we make query to this view two twice: one for TCP and then
    for local protocol.

    Checked on 6.0.0.511 (Windows/Linux); 5.0.2.1550;  4.0.6.3165; 3.0.2.32670, 3,0,1,32609
