I've seen this asked several times, but not with a good resolution. I have the following string:
$string = "<p>Résumé</p>";
I want to print or echo the string, but the output will return <p>R�sum�</p>. So I try htmlspecialchars() or htmlentities() which outputs <p>Résumé<p> and the browser renders <p>Résumé<p>. I want it, obviously, to render this:
Résumé
And I'm using UTF-8:
header("Content-type: text/html; charset=UTF-8");
What am I missing here? Why does echo and print output a � for any special character? To clarify, the string is actually an entire html file stored in a database. The real world application is not just that one small line.
After much banging-head-on-table, I have a bit better understanding of the issue that I wanted to post for anyone else who may have had this issue.
While the UTF-8 character set will display special characters on the client, the server, on the other hand, may not be so accomodating and would print special characters such as à and è as � and �.
To make sure your server will print them correctly, us the ISO-8859-1 charset:
<?php
/*Just for your server-side code*/
header('Content-Type: text/html; charset=ISO-8859-1');
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"><!-- Your HTML file can still use UTF-8-->
<title>Untitled Document</title>
</head>
<body>
<?= "àè" ?>
</body>
</html>
This will print correctly: àè
Edit (4 years later):
I have a little better understanding now. The reason this works is that the client (browser) is being told, through the response header(), to expect an ISO-8859-1 text/html file. (As others have mentioned, you can also do this by updating your .ini or .htaccess files.) Then, once the browser begins to parse that given file into the DOM, the output will obey any <meta charset=""> rule but keep your ISO characters in tact.
You can have a mix of PHP and HTML in your PHP files... just do something like this...
<?php
$string = htmlentities("Résumé");
?>
<html>
<head></head>
<body>
<p><?= $string ?></p>
</body>
</html>
That should output Résumé just how you want it to.
If you don't have short tags enabled, replace the <?= $string ?> with <?php echo $string; ?>
So I try htmlspecialchars() or htmlentities() which outputs <p>Résumé<p> and the browser renders <p>Résumé<p>.
If you've got it working where it displays Résumé with <p></p> tags around it, then just don't convert the paragraph, only your string. Then the paragraph will be rendered as HTML and your string will be displayed within.
In PHP there is a pretty good function utf8_encode() to solve this issue.
echo utf8_encode("Résumé");
//will output Résumé instead of R�sum�
$str = "Is your name O\'vins?";
// Outputs: Is your name O'vins? echo stripslashes($str);
This works for me:
Create/edit .htaccess file with these lines:
AddDefaultCharset UTF-8
AddCharset UTF-8 .php
If you prefer create/edit php.ini:
default_charset = "utf-8"

Try This
Input:
<!DOCTYPE html>
<html>
<body>
<?php
$str = "This is some <b>bold</b> text.";
echo htmlspecialchars($str);
?>

</body>
</html>
Output:
This is some <b>bold</b> text.

This works for me. Try this one before the start of HTML. I hope it will also work for you.
<?php header('Content-Type: text/html; charset=iso-8859-15'); ?>
<!DOCTYPE html>
<html lang="en-US">
<head>The following worked for me when having a similar issue lately:
$str = iconv('iso-8859-15', 'utf-8', $str);
