Question

Iam using codeIgniter and having the following settings but still my webpage is displaying "?" in case of special characters.

Database - UTF-8 encoding Table - UTF-8 column -UTF-8 in the html file I have the following line added

<? header("Content-Type: text/html; charset=UTF-8"); ?>

37 degrees centigrade is displayed as "maintained at 37�C"

and other special characters are also wrongly displayed.

Answer 1

Set this

In config.php

$config['charset'] = "UTF-8";

In database connection

$db['default']['char_set'] = "utf8"; 
$db['default']['dbcollat'] = "utf8_unicode_ci";

In Header of your file

echo meta('Content-type', 'text/html; charset=utf-8', 'equiv');
// Generates:  <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
