ruby 2.0编码下的Serenity odt:：CompatibilityError

这里有一个问题：在ruby 1.8.7下工作得很好，但在ruby 2.0.0p195下会发生一些事情。使用相同的模板和ruby代码时，会出现以下错误：

incompatible character encodings: ASCII-8BIT and UTF-8 (Encoding::CompatibilityError)

此解决方案对我没有影响：

我的环境：Ubuntu 12.04.2 LTS x86\u 64 3.2.0-49-generic，rvm 1.21.2。

通过添加字符串

content=content.force\u编码（'UTF-8'）

在/home/michael/.rvm/gems/ruby-2.0.0-p195/gems/serenity-odt-0.2.1/lib/serenity/template.rb

def process context
  tmpfiles = []
  Zip::ZipFile.open(@template) do |zipfile|
    %w(content.xml styles.xml).each do |xml_file|
      content = zipfile.read(xml_file)
      content = content.force_encoding('UTF-8')
      odteruby = OdtEruby.new(XmlReader.new(content))
      out = odteruby.evaluate(context)

      tmpfiles << (file = Tempfile.new("serenity"))
      file << out
      file.close

      zipfile.replace(xml_file, file.path)
    end
  end
end

def进程上下文
tmpfiles=[]
Zip:：ZipFile.open（@template）do | ZipFile|
%w（content.xml styles.xml）。每个do | xml|u文件|
content=zipfile.read（xml\u文件）
content=content.force_编码（'UTF-8'）
odteruby=odteruby.new（XmlReader.new（content））
out=odteruby.evaluate（上下文）
TMP文件
