converting unicode to normal characters before displaying on webpage

Question

I'm using openinviter class to import the contacts from email. However, it displays the Unicodes of non-english characters (for example, polish), such as u0117 (and similar type of other codes) instead of normal characters. Is there anyway that I can convert the unicodes to characters and then display them?

Here is the original code of the page: http://pastebin.com/d0tkpxbv

Thanks.

I just added the link in my original post, please check. Thank you. — Lucka, Jan 08 '11 at 16:30

The following code allows you to decode the characters as well as re-encode them if necessary

Code :

if (!function_exists('codepoint_encode')) {

    function codepoint_encode($str) {
        return substr(json_encode($str), 1, -1);
    }

}

if (!function_exists('codepoint_decode')) {

    function codepoint_decode($str) {
        return json_decode(sprintf('"%s"', $str));
    }

}

How to use :

header('Content-Type: text/html; charset=utf-8'); 

var_dump(codepoint_encode('ඔන්ලි'));
var_dump(codepoint_encode('සින්ග්ලිෂ්'));

var_dump(codepoint_decode('\u0d94\u0db1\u0dca\u0dbd\u0dd2'));
var_dump(codepoint_decode('\u0dc3\u0dd2\u0db1\u0dca\u0d9c\u0dca\u0dbd\u0dd2\u0dc2\u0dca'));

Output :

string(30) "\u0d94\u0db1\u0dca\u0dbd\u0dd2"
string(60) "\u0dc3\u0dd2\u0db1\u0dca\u0d9c\u0dca\u0dbd\u0dd2\u0dc2\u0dca"
string(15) "ඔන්ලි"
string(30) "සින්ග්ලිෂ්"

If you want more complex functionality, see How to get the character from unicode code point in PHP?.

In your decode function you need to escape double quotes that could be in _$str_. Otherwise bad things will happen. — datashaman, Nov 14 '17 at 06:44

Use preg_replace() to convert the value to its hexadecimal numeric entity:

<?php
$text = 'Wladisu0142aw';
$text = preg_replace('/u([0-9a-f]{4})/i', '&#x$1;', $text);
echo $text;  //displays Wladisław
?>

This does not address the _backslash_ that is usually just before the _u_. Those will be left behind in the result. The _$text_ variable should be: _Wladis\u0142aw_ – datashaman Nov 14 '17 at 06:47
