# title:        Field name max length check wrongly if national characters specified
# decription:   
#                   Confirmed bug on 3.0.4.32972, got error:
#                       Statement failed, SQLSTATE = 22001
#                       arithmetic exception, numeric overflow, or string truncation
#                       -string right truncation
#                       -expected length 31, actual 31
#               
#               	Though this ticket was fixed only for FB 4.x, Adriano notes that error message
#               	was corrected in FB 3.0.6. Thus we check both major versions but use different
#               	length of columns: 32 and 64.
#               	Checked on:
#               		4.0.0.1753 SS: 1.630s.
#               		3.0.6.33237 SS: 0.562s. 
#               
#                   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 (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, 3.0.8.33420
#                           * Linux:   4.0.0.2377, 3.0.8.33415
