在windows上使用AscidActor maven插件时强制在JRuby中编码

在Windows上使用AscidActor maven插件，我们在执行目标进程AscidOcs时遇到编码不兼容错误

我们尝试了0.1.4版本的插件和master的最新快照

当将cruby与AscidActor gem一起使用时，我们没有得到这个错误，因此它认为问题在于jruby执行环境

在Mac上，我们通过设置JAVA_TOOL_OPTIONS=“-DFile=encoding.UTF-8”解决了相同的错误，但在Windows上这没有效果

---

我们如何强迫jruby使用UTF-8？

我们通过在asciidoctor java集成jar中编辑asciidoctor源代码，强制gems/asciidoctor-0.1.4/lib/asciidoctor.rb中的Encoding.default_external=Encoding:：UTF_8，解决了这个问题。虽然不是一个优雅的解决方案，但它可以工作
