Strange symbols in log-output

I started to see strange output in my log files:

2018-11-14 14:04:21,180 [main] [34mINFO[0;39m com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Shutdown initiated...
2018-11-14 14:04:21,186 [main] [34mINFO[0;39m com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Shutdown completed.`

I don't know what does [34m or [0;39m mean and why it is here.

My logback.xml configuration:

 <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

    <file>server.log</file>

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

      <fileNamePattern>server.%d{yyyy-MM-dd}.%i.log</fileNamePattern>

      <timeBasedFileNamingAndTriggeringPolicy

              class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">

        <maxFileSize>50MB</maxFileSize>

      </timeBasedFileNamingAndTriggeringPolicy>

      <maxHistory>30</maxHistory>

    </rollingPolicy>

    <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">

      <charset>UTF-8</charset>

      <layout class="ch.qos.logback.classic.PatternLayout">

          <pattern>%d [%thread] (%level) %logger{50} - %msg%n</pattern>

      </layout>

    </encoder>

  </appender>

Those are escape sequences to color the output. See ANSI escape codes
