Salt发布2014.7.0后，及时进行了更新，测试下来，在上一版本正常运行的操作，这一版本却出现报错。公司的好多服务由于历史原因，配置文件延续下来，使用的是gb2312编码，其中还有中文注释。在使用salt进行管理的时候，在Master端会报UnicodeDecodeError错误。
执行配置文件更新，并重启服务操作：
salt 'zhaogb-202' state.sls update_conf.manager
manager.sls是更新Manager服务配置文件的模板：
ma_watch: service: - name: ManagerServerd - running - reload: True - watch: - file: /home/ManagerServer/config.xml /home/ManagerServer/config.xml: file.managed: - source: salt://dzh_store/conf_file/ManagerServer/config.xml - user: root - group: root - mode: 644 - backup: minion
执行该更新操作后，会报如下错误：
[ERROR ] An un-handled exception was caught by salt's global exception handler:
UnicodeDecodeError: 'utf8' codec can't decode byte 0xca in position 18: invalid continuation byte

UnicodeDecodeError: 'utf8' codec can't decode byte 0xca in position 18: invalid continuation byte执行返回报错，但是Minion端配置文件已经更新，并且服务重启载入新的配置文件。也就是说，这个报错产生在Master端，对Minion没有影响。所有操作都在上一个版本（2014.1.0）验证过，没有任何问题。排查下来，找到
/usr/lib/python2.6/site-packages/salt/output/nested.py
这个文件，与上一个版本相比，增加了一个ustring方法,其中定义了一个带默认值encoding='utf-8'参数，问题就出现在这里。
2014.7.0 nested.py
由于我的配置文件采用gb2312编码，所以在对msg进行decode操作时使用utf-8会报错，再增加一个try,except调试来解决这个问题，修改后的代码如下：
也就是修改了except，再做一次判断。
至此，这个问题暂时解决了，无论是utf-8配置文件，还是gb2312配置文件，都通过，不确定是否会影响Salt本身的功能。
