Hello, Friends!

I use Sony Reader T1, it is first wifi e-bookreader of sony Japan.
But it has some problem. Sony reader T1,PRS650 don't work offline web page reading tool.
In case of instapaper, each section(or chapter)'s header is problem.
When I download instaper with defalt calibre recepie, each header is
Code:
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US">
<head>
But transpher this epub file to Sonyreader(jp) almost characeters are ??????. I can't read!
So, it is very hard to change webpage to sonyreader in Japanese.
To read epub file on sonyreader change each sections header following:
Code:
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="ja" xmlns:xml="http://www.w3.org/XML/1998/namespace">
<head>
I want to know how to write in default recipe to change header.
