使用logback时输出log内容乱码

已经在 pom.xml 中加入相关 jar

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>log4j-over-slf4j</artifactId>
            <version>1.7.21</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.1.8</version>
        </dependency>

logback.xml文件中已加入charset

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="true" scanPeriod="5 seconds">
    <appender name="WEB" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <ImmediateFlush>true</ImmediateFlush>
            <pattern>%d [%t] %-5p %c - %m%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <logger name="org.nutz" additivity="false" level="info">
        <appender-ref ref="WEB"/>
    </logger>
    <logger name="org.quartz" additivity="false" level="info">
        <appender-ref ref="WEB"/>
    </logger>
    <root level="debug">
        <appender-ref ref="WEB"/>
    </root>
</configuration>

但是输入的log中还是乱码。请问该如何解决
