(Problem resolved) The error text is replaced by the Specials symbol

Question

(Problem resolved) sadly that i don't remember what exactly helped. I changed language in whole system, installed postgres, and create new container from new image with postgres

Old question: I would like to understand what is the problem to solve this, but because the error message is replaced with the specials symbol I can't.

Screenshot:

• The database customer exists on server xsakonServer
• Default encoding is set to UTF-8 (Screenshot)

here is application.yml file:

server:
  port: 8080

spring:
  application:
    name: customer
  datasource:
    password: password
    url: jdbc:postgresql://localhost:5432/customer
    username: xsakon
  jpa:
    hibernate:
      ddl-auto: create-drop
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQLDialect
        format_sql: 'true'
    show-sql: 'true'

docker-compose.yml file:

services:
  postgres:
    container_name: postgres
    image: postgres
    environment:
      POSTGRES_USER: xsakon
      POSTGRES_PASSWORD: password
      PGDATA: /data/postgres
    volumes:
      - postgres:/data/postgres
    ports:
      - "5432:5432"
    networks:
      - postgres
    restart: unless-stopped

  pgadmin:
    container_name: pgadmin
    image: dpage/pgadmin4
    environment:
      PGADMIN_DEFAULT_EMAIL: ${PGADMIN_DEFAULT_EMAIL:-pgadmin4@pgadmin.org}
      PGADMIN_DEFAULT_PASSWORD: ${PGADMIN_DEFAULT_PASSWORD:-admin}
      PGADMIN_CONFIG_SERVER_MODE: 'False'
    volumes:
      - pgadmin:/var/lib/pgadmin
    ports:
      - "5050:80"
    networks:
      - postgres
    restart: unless-stopped


networks:
  postgres:
    driver: bridge

volumes:
  postgres:
  pgadmin:

I already tried replace

password: password
username: xsakon

to

password: 'password'
username: 'xsakon'

in application.yml file. But result is the same

• Added parameter -Duser.language=en to Java VM options (Screenshot) applied then restarted project but it didn't help

I hope somebody find out what is the error massage, then I'll fix the problem by myself
