Copying from file: read psql message on windows with UTF8 - windows

Question

I'm trying to import csv file to postgres with COPY command.
As I've received well known 'ERROR: character with byte sequence 0xd0 0x9f in encoding "UTF8" has no equivalent in encoding "WIN1252"' I changed my client_encoding to utf8.
Now I'm getting completely unreadable message
ПОМИЛКÐ: Ð²Ñ–Ð´Ð½Ð¾ÑˆÐµÐ½Ð½Ñ "mytab" не Ñ–Ñнує
I tried to change console codepage by chcp 65001 but with no luck.
Can anybody help me with that extraordinary rare and complex task - to import csv to database?

Answer 1

Solution:
I would suggest, that problem is due to UA or RU localization of installed DB.
Switching DB lang should help (at least hepled me):
SET lc_messages TO 'en_US.UTF-8';
Please try on your PC and let me know if that helps.
My investigation:
In the powerShell I all the time getting an error but with:
ERROR: character with byte sequence 0xd0 0x9f in encoding "UTF8" has no equivalent in encoding "WIN1252"
When I swith encoding to UTF-8 with comand:
SET client_encoding TO 'UTF8';
I'm starting to get the same not readable symbols, but if I going to pgAdmin4 and run the same command it gives me well explained error in UA lang:
ERROR: ПОМИЛКА: insert або update в таблиці "exam_results" порушує обмеження зовнішнього ключа "exam_results_subject_id_fkey"
