我正在用 ruby​​ 编写这个机器人并遇到了麻烦，这比我想象的要复杂得多。我阅读了许多类似的文章，但没有任何帮助。

它可能与 watir 无关，但具体来说，我说它是。另外，我在 Fedora 上。这是我尝试过的：

table = browser.table(:index , 7)
puts table[1][1].text

html 表格片段类似于：

<table>
 <tr>
   something...
 </tr>
 <tr>
  <td/>
  <td>
   Likiškėlių 
  </td>
 </tr>
</table>

我明白了

    from watir.rb:25:in `<main>'

我也试过：

 .gsub!(/\P{ASCII}/, '')
 .delete!("^\u{0000}-\u{007F}")

变化，但没有成功。请帮忙！为什么编码这么复杂？我一无所知。

编辑：实际上，如果有帮助，我不需要打印字符串，只需将其写入文件，但错误是相同的。

我的 ruby​​ 版本是：ruby 1.9.3p392（2013-02-22 修订版 39386）[i386-linux]

编辑：我也试过：

# encoding: ASCII-8BIT
or 
# encoding: utf-8
with 
puts table[1][1].text.length

但仍然是同样的错误

编辑因为它甚至不会显示 .bytesize ，我敢打赌它是 watir。有什么建议么？

好的，我得到了一些东西。我将我的 watir 浏览器从 firefox 更改为 chrome。现在我得到编码的字符串并且没有错误。中提琴！

安装“json”或“oj”gem 将解决这个问题。

有关支持的 JSON 引擎的完整列表，请参阅https://github.com/intridea/multi_json。
