导轨：地质套件"incompatible character encodings: UTF-8 and ASCII-8BIT "

Question

我只想将geokit gem与以下俄语字符一起使用（从rails控制台进行测试）：

Geokit::Geocoders::GoogleGeocoder.geocode 'минск'

但是得到下一个错误：

Encoding::CompatibilityError: incompatible character encodings: UTF-8 and ASCII-8BIT
        from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/geokit-1.6.5/lib/geokit/geocoders.rb:464:in `do_geocode'
        from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/geokit-1.6.5/lib/geokit/geocoders.rb:129:in `geocode'
        from (irb):16
        from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/railties-3.2.1/lib/rails/commands/console.rb:47:in `start'
        from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/railties-3.2.1/lib/rails/commands/console.rb:8:in `start'
        from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/railties-3.2.1/lib/rails/commands.rb:41:in `<top (required)>'
        from script/rails:6:in `require'
        from script/rails:6:in `<main>'

下一个可能的解决方案于事无补：

Geokit::Geocoders::GoogleGeocoder.geocode 'минск'.force_encoding('UTF-8')
Geokit::Geocoders::GoogleGeocoder.geocode(CGI.escape('Минск'))
#in config/environment.rb
Encoding.default_external = Encoding::UTF_8 
Encoding.default_internal = Encoding::UTF_8

什么可以帮助解决这个问题？我对google-places宝石也有同样的问题。

Answer 1

这里的问题是记录器。

https://github.com/imajes/geokit-gem/blob/master/lib/geokit/services/google3.rb#L49

在这一行，它连接UTF-8 address字符串和ASCII json响应。修复方法是在这行之前添加以下代码：

json.force_encoding('utf-8') if json.respond_to?(:force_encoding)

您可以执行此操作并发送提取请求。刚刚对Nomatim地理编码器做了同样的操作。
