我正在用ruby寫這個bot，遇到了麻煩，這顯示出來比我想象的要複雜得多。我讀了很多類似的文章，但沒有什麼幫助。Watir不兼容的字符編碼
它可能與watir無關，但只是爲了具體我說的是。另外，我在Fedora上。這是我的嘗試：
table = browser.table(:index , 7)
puts table[1][1].text
HTML表格片段是這樣的：
<table>
<tr>
something...
</tr>
<tr>
<td/>
<td>
Likiškėlių
</td>
</tr>
</table>
我得到

我也嘗試：
.gsub!(/\P{ASCII}/, '')
.delete!("^\u{0000}-\u{007F}")
變化，但它沒有解決。請幫忙！爲什麼編碼如此複雜？我無能爲力。
編輯：實際上，如果有幫助，我不需要打印字符串，但只寫入文件，但錯誤是相同的。
和我的紅寶石版本是：紅寶石1.9.3p392（2013年2月22日修訂39386）[i386的Linux的]
編輯：我也試過：
# encoding: ASCII-8BIT
or
# encoding: utf-8
with
puts table[1][1].text.length
仍然在同樣的錯誤
編輯因爲它甚至不會顯示.bytesize，我敢打賭它是watir。有什麼建議麼？
