# title:        Unexpected "cannot transliterate" error
# decription:
#                   05-mar-2021. Re-implemented in order to have ability to run this test on Linux.
#                   Test encodes to UTF8 all needed statements (SET NAMES; CONNECT; DDL and DML) and stores this text in .sql file.
#                   NOTE: 'SET NAMES' contain character set that must be used for reproducing problem (WIN1251 in this test).
#                   Then ISQL is launched in separate (child) process which performs all necessary actions (using required charset).
#                   Result will be redirected to log(s) which will be opened further via codecs.open(...encoding='cp1251').
#                   Finally, its content will be converted to UTF8 for showing in expected_stdout.
#                   Checked on:
#                   * Windows: 4.0.0.2377, 3.0.8.33423; old version: 3.0.4.32972, 3.0.2.32703, 3.0.1.32609, 3.0.0.32483, 2.5.9.27152
