# Lynx patch to ignore xml encoding if charset is specified in Content-Type header
## Problem
Some sites (2chcopipe.com, digital-thread.com) use
incorrect <?xml encoding value.
Lynx displays garbled characters.
Content-Type: text/html; charset=euc-jp
...
<?xml version="1.0" encoding="UTF-8"?>
...
<meta http-equiv="Content-Type" content="text/html; charset=euc-jp" />
...
(euc-jp encoded body text)
## Patch
Change to ignore xml encoding if charset is specified in Content-Type HTTP response header.
## TODO
* Use xml encoding like META charset (not only check utf-8)
