简单方法：调外部命令 unrtf 或者 pandoc 或者用 https://github.com/clbustos/rtf

@luikore 你说的这个包具体怎么用呢？有没有类似 rtf.to_html 的方法？

pandoc 不支持 rtf 吧？

require 'pandoc-ruby'  

rtf_str = "{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Tahoma;}} {\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\f0\fs17 Received Billing Agreement 12 04 12 KC \par Number of properties - 40\par \par \ul\b ***VERIFY WITH JOHN IF THE PROPERTY HE IS CALLING IN IS A FANNIE MAE OR NOT***\par \par \par 1) On Vacant Fannie Mae properties ABC Company to fannie mae key- \par 2) On occupied properties ABC Company to random key \par 3) NON-FANNIE MAE PROPERTIES - KEY TO 60-70 and L-S\ulnone\b0\par \ul\b 4)\ulnone\b0 .

puts PandocRuby.convert(rtf_str, :from => rtf, :to => :html)
