maven编译带中文的工程时出现syntax error的有关问题

在编译带中文的maven工程时，尽管pom文件中设置了<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>，但仍然会报错，如下信息：

[ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.7.2:scr (generate-scr-scrdescriptor) on project toolkit.monitor.manager: Execution generate-scr-scrdescriptor of goal org.apache.felix:maven-scr-plugin:1.7.2:scr failed: syntax error @[193,1] in file:/E:/wso2-svn/toolkit.monitor.manager/src/main/java/com/shuhao/toolkit/monitor/manager/WarnHandler.java -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException

通过clean install -X命令执行编译查看详细报错信息，发现其中有一行这样的错误：

Caused by: com.thoughtworks.qdox.parser.ParseException:syntax error@[193,1] in file:/E:/wso2-svn/toolkit.monitor.manager/src/main/java/com/shuhao/toolkit/monitor/manager/WarnHandler.java

后面我终于发现了是因为文件中存在某些中文字符导致编译打包出错，只要将这些中文换成其他的中文即可通过编译。不过还不清楚为什么有的中文编译不过去，知道的大神指点下，谢谢
