# title:        Attempt to create mapping with non-ascii user name which is encoded in SINGLE-BYTE codepage leads to '-Malformed string'
# decription:   
#                   Reproduced 'malformed string' error on: 3.0.4.33053, 4.0.0.1172.
#               
#                   03-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 (WIN1252 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='cp1252').
#                   Finally, its content will be converted to UTF8 for showing in expected_stdout.
#               
#                   NB: different data are used for FB 3.x and 4.x because DDL in 4.x allows to store names with length up to 63 character.
#                   See variables 'mapping_name' and 'non_ascii_user_name'.
#                   FB 3.x restricts max_length of DB object name with value = 31 (bytes, not character!).
#               
#                   Checked on:
#                       * Windows: 4.0.0.2377, 3.0.8.33420
