View Full Version : encoding HTTP header

11-05-2009, 02:48 PM
I have a doctype set to XHTML 1.0 Strict.
I want to use the UTF-8 charset.
If I validate the page it says the following:
The character encoding specified in the HTTP header (iso-8859-1) is different from the value in the <meta> element - utf-8. I will use the value from the HTTP header (iso-8859-1) for this validation.

So how do I change the encoding in the HTTP header? I did check at Modify --> Page Properties --> Title/Encoding and it says there that the encoding is Unicode 5.0 UTF-8.

So what to do? I don't want to use iso-8859-1, because then I have to code for example a normal "&" as "&amp;" which I can do of course, but first this gives me more and unnecessary work and second if I parse for example a RSS feed and they used the normal "&" then I have an error.

I hope that someone can give me advice on this because it start to drive me crazy :roll:

Thanks in advance!

The characterset should be dfined in the XML declaration, the first lines of your document.

Thanks for your reply!
Sorry... I forgot to mention in my previous post.
I did try already <?xml version="1.0" encoding="utf-8" ?> in the first line without the <meta> element version, but then the whole page won't load at all. It gives a white page with a server alert that there is an error on the first line.

Then it sounds like something else is wrong with your page.
There should be no problems declaring the document as XML.

I really don't know what I'm doing wrong, Domedia.

Can you please take a look at the source of the following documents? Perhaps you can see what I'm doing wrong. If you validate indexter2.php then it says that he can't see a doctype at all.


XML decleration:

Thanks in advance!

it looks like a php error

Okay! I did a test and removed the php includes (RSS feeds) and saved the page as a html document. The page loads fine like this, but I still get the encoding mismatch warning. I really can't change the encoding in the HTTP header from iso-8859-1 to UTF-8 even with the XML declaration in the first line.

This is what I have above the <head>:
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">


Validation output:
http://validator.w3.org/check? (http://validator.w3.org/check?uri=http%3A%2F%2Fwww.gentlemedia.nl%2Findext er2.htm&charset=%28detect+automatically%29&doctype=Inline&group=0&st=1&accept=application%2Fxml%2Capplication%2Fxhtml%2Bx ml%2Ctext%2Fhtml%3Bq%3D0.9%2Ctext%2Fplain%3Bq%3D0. 8%2Cimage%2Fpng%2C*%2F*%3Bq%3D0.5&accept-language=en-us&user-agent=W3C_Validator%2F1.654)

Well, I finally found the solution how I change the HTTP header in my PHP document. Instead of using in the first line:
<?xml version="1.0" encoding="UTF-8" ?>
I had to code it this way:
<?php header('Content-Type:text/html; charset=UTF-8'); ?>

But!!! I thought with UTF-8 a normal "&" would validate, but unfortunately it doesn't. It still says that I have to use "&amp;" instead.

Hmmmm... confused!

I'm a happy coder again :)

Problem solved! It had noting to do with the encoding in the HTTP header, but was indeed a PHP issue. I had to add .htmlentities() to some variables in the RSS to HTML script.

I wanna thank those who took the time to help me.
