我正在用ruby写这个bot，遇到了麻烦，这显示出来比我想象的要复杂得多。我读了很多类似的文章，但没有什么帮助。Watir不兼容的字符编码
它可能与watir无关，但只是为了具体我说的是。另外，我在Fedora上。这是我的尝试：
table = browser.table(:index , 7)
puts table[1][1].text
HTML表格片段是这样的：
<table>
<tr>
something...
</tr>
<tr>
<td/>
<td>
Likiškėlių
</td>
</tr>
</table>
我得到

我也尝试：
.gsub!(/\P{ASCII}/, '')
.delete!("^\u{0000}-\u{007F}")
变化，但它没有解决。请帮忙！为什么编码如此复杂？我无能为力。
编辑：实际上，如果有帮助，我不需要打印字符串，但只写入文件，但错误是相同的。
和我的红宝石版本是：红宝石1.9.3p392（2013年2月22日修订39386）[i386的Linux的]
编辑：我也试过：
# encoding: ASCII-8BIT
or
# encoding: utf-8
with
puts table[1][1].text.length
仍然在同样的错误
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？
