尝试形成POST查询时机械化Iconv::IllegalSequence

Question

下面的代码引发了前面提到的错误，我该如何修复呢？

require 'mechanize'
m = WWW::Mechanize.new
p = m.get('http://art-mobile.com.ua/register.php')
f = p.forms.first
f.submit(f.buttons.last)

为了以防万一，下面是我的框上错误的完整描述

BTW this solution不能工作

看起来解决方案是稍微重写一下gem，以便它在初始化新页面时将页面的编码转换为utf-8，将@encoding var更改为utf-8并将原始编码存储在另一个文件中，并进行必要的更改以强制gem在形成查询时使用原始编码。
