I'm trying to make a script that gets data out from an sqlite3 database, but I have run in to a problem.

The field in the database is of type text and the contains a html formated text. see the text below

<html>
<head>
<title>Yahoo!</title>
</head>
<body>
<style type="text/css">
html {}
.yshortcuts {border-bottom:none !important;}
.ReadMsgBody {width:100%;}
.ExternalClass{width:100%;}
</style>

When you open the file you want to write to, open it with a specific encoding that can handle all the characters.

with open('filename', 'w', encoding='utf-8') as f:
    print(r['body'], file=f)
