各位论坛大神，最近在用rstudio玩shiny包，被编码问题折磨的死去活来 :cry: 终于决定发个处女贴来向大家求助求助，看看大家在这方面是否有经验指导一下：
在代码运行过程中，出现了：
但同时出现了提示warning：
点击stop停止运行后，再次运行就会报下面的错误：
在geogle的论坛里面我发现过类似的问题：
https://groups.google.com/forum/#!topic/shiny-discuss/lq5hZ81mLCo
但是他的windows是英文版，后来改中文版就成功了。
我的shiny版本是1.1最新的，Rstudio执行sessionInfo()的信息如下：
同一个组几位同学都是UTF-8的问题，运行不成功，求帮助。我们也有到shiny的官网看例子：

我自己的代码用到了rcharts封装百度的echarts，echarts相关js的路径目录用
r1$setLib('C://Users//lzkun_000//Documents//R//win-library//3.1//rCharts//libraries//echarts')指定：
server.R:
