汉字编码问题 - Heroku

Question

我有一个小JRuby Sinatra应用程序使用Jieba for JRuby gem来标记中文句子。

当运行我的本地机器上的应用程序，我没有任何编码问题：

curl --data "text=Ruby China，对！经是国内最权威的 Ruby 社区，拥有国内所有资深的 Ruby 工程师。&key=myKey" http://localhost:9292 
# => ["Ruby", "China", "经是", "国内", "权威", "社区", "拥有", "所有", "资深", "工程师"] 

然而，当我推应用的Heroku，我有编码问题：

curl --data "text=Ruby China，对！经是国内最权威的 Ruby 社区，拥有国内所有资深的 Ruby 工程师。&key=XWtrws324FGH675BV" http://secure-wildwood-3084.herokuapp.com 
# => ["\"Ruby\", \"China\", \" \", \" 。\""] 

我试图强制编码为UTF-8 .force_encoding("utf-8")，但仍然存在问题。我也尝试将Heroku上的LANG配置变量设置为LANG: zh_CN.UTF-8，但这并没有什么区别。

我用来部署应用程序的方法在README中。这是推动应用的Heroku当输出：

Answer 1

查看输出/项目就好像是用相当老的JRuby的点点滴滴，在这种情况下，最重要的事情是使用JRuby版本（你可能做的当地有一个不同）：1.6.7https://github.com/diasks2/jieba-heroku/blob/master/pom.xml#L14

我把那个JRuby的1.7.16和捆绑更新他人从以下输出，以及：

[INFO] Installing json 1.8.0 
[INFO] Installing rack 1.4.1
