# title:        substring similar - extra characters in the result for non latin characters
# decription:   
#                   Confirmed regression on build 4.0.0.1629, 4.0.0.1631 
#               	Worked as expected on 4.0.0.1535 (build 24.06.2019, before replacement old regexp library with 're2')
#                   Works fine on: 4.0.0.1632 (build 19.10.2019)
#               
#                   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
#                   * Linux:   4.0.0.2379
