Ruby Mechanize因编码错误而停止：由于输入错误，输入转换失败，字节0xFA 0xBA 0x3C 0x2F

Question

我使用Ruby mechanize（Ruby版本：2.3.1p112，Mehanize版本：2.7.5）来抓取网页。 由于输入错误导致某些页面压缩＆＃34;输入转换失败＆＃34; 我要抓的页面是http://www.jra.go.jp/JRADB/accessD.html 和我的代码并在下面执行日志。

agent = Mechanize.new
agent.log = Logger.new(STDOUT)
agent.post('http://www.jra.go.jp/JRADB/accessD.html', { "cname" => "pw01bmd0006201705080220171224/7A" })

我理解这是字符编码问题的原因，如果发生解析错误，我想忽略。我怎么能这样做？
