# title: Query cannot be executed if win1251 characters used in field aliases
# decription:
# Test prepares file that will serve as input SQL script and will have CYRYLLIC names for field aliases.
# File has name = 'tmp_non_ascii_chk_5389.sql' and is encoded to windows-1251 codepage.
# Checked on 4.0.0.639.
# 30.10.2019 checked on:
# 4.0.0.1635 SS: 2.782s.
# 4.0.0.1633 CS: 3.515s.
# NB: old checked on: 4.0.0.639 - did pass without using codecs! Strange!
#
# 13.04.2021. Adapted for run both on Windows and Linux. Checked on:
# Windows: 4.0.0.2416
# Linux: 4.0.0.2416
#
# tracker_id: CORE-5389
