Description

When I tried to log a Japanese string the output was scrambled in both the Console and a log file.

For example,
logger.warn("日本語テスト"); // (Japanese test)

came out as
15:07:00.184 [main] WARN test.JapaneseTest - 譌･譛ｬ隱槭ユ繧ｹ繝?

This is the log4j2.xml configuration:

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="warn">
    <appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout>
                <pattern>%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n
                </pattern>
            </PatternLayout>
        </Console>
        <File name="tracelog" fileName="trace-log.txt" immediateFlush="true" append="false">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </File>
    </appenders>
    
    <loggers>
        <root level="trace">
            <appender-ref ref="Console"/>
            <appender-ref ref="tracelog"/>
        </root>
    </loggers>
</configuration>
