write html-headers (utf-8)

db · May 30, 2005

Hello all,

I hope this is the correct newsgroup for this question.

Does anybody know how I can write a html-header with python(cgi)?
The problem is, I have a few html templates in which I have a header e.g:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

In this template I write a few Mysql variables.
Those variable often have german characters. This characters (GÃ¶sing in
stead of Gösing). The german characters in the html template are shown
correctly.

If I change the character encoding with the browser to utf-8, all the characters are shown correctly.
As you can see, I put in the header of the html template that the encoding
is UTF-8, the browser still shows windows ISO-8859-15. Can I write the
header with python so the browser uses the utf-8 encoding?

My hosting providor uses fedora core 2, Python 2.2.3, MySQLdb. Mysql 3.23.58

I googled for hours, but I can't find the answer. I hope ypu can help me.

Thanks in advance.

The problem is then with these variables: apparently, the Mysql
variables are encoded in iso-8859-15, and you need to recode them
to UTF-8 first before putting them into the template.

var = var.decode("iso-8859-15").encode("utf-8")

As you can see, I put in the header of the html template that the encoding
is UTF-8, the browser still shows windows ISO-8859-15. Can I write the
header with python so the browser uses the utf-8 encoding?

The problem is not the header, but the body. The browser sees your claim
that the page is UTF-8, but doesn't believe it. This is because it tries
to interpret the page as UTF-8, and then finds invalid byte sequences
(your latin-9 characters), and then knows that the page *can't* be
UTF-8. It then guesses that the page must be latin-something. That guess
is wrong, of course, also, because some characters in the page are
utf-8, and others latin-9. This is invalid HTML.

Martin

Does your browser send a Content-Type HTTP header (don't confuse this with
the HTML <head> part)? If it does and it specifies a charset, this will
override your <meta http-equiv>. Often iso-8859-1 is the default charset
for the Content-Type header.

If you are using CGI you can set the Content-Type header directly. Before you output your HTML do
print "Content-Type: text/html; charset=UTF-8"
print # blank line, end of headers
