javascript encodeURIComponent equivalent in php - php

I need to convert %F3%BE%AE%A2 to this char "󾮢" in PHP. When I tried using
rawurldecode('%F3%BE%AE%A2');
then it gives 2 chars instead of 1 char.
How can I convert it properly?
EDIT:
To be more specific it's an UTF-16 surrogate char.it gives \udbba\udfa2 in javascript.Now
if i want to send data via javascript API then i could easily send "󾮢" as a single character.
But for security reasons i need to use PHP.That's where the problem starts.Decoding '%F3%BE%AE%A2' with rawurldecode() along with utf-8 header doesn't seem to be giving me the char i want.
Wish i have explained it.Thanks for your appreciations.

Actually rawurldecode() is giving you the correct result. That character consists of four bytes when encoded in utf-8 and the rule in url encoding is to convert each byte to %XX notation. rawurldecode() is giving you back those 4 bytes but probably you have not set your page's encoding to utf-8 so your browser is misinterpreting those bytes. add this to your <head>:
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
and you should see the right character.
This is a test page I made:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
</head>
<body>
<?php echo rawurldecode('%F3%BE%AE%A2'); ?>
</body>
</html>
what I see in my browser:
󾮢
exactly the character you want to see.

Incorrect encoding on Php file but not on Html file

I write this code in Html file
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-15" />
</head>
<body>
Try with special character (ì)
</body>
</html>
When I display my html file it's all ok
Try with special character (ì)
But when I rename my html file in php file this is the result
Try with special character (�)
Someone can help me to understand?
You could try with UTF-8:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
Have a look at the PHP function mb_internal_encoding. It sets the character set that PHP will use internally. If you add this at the top of your HTML:
<?php
mb_internal_encoding("iso-8859-15");
?>
Your HTML should show fine if the file is in ISO-8859-15. What happens is that PHP interprets the HTML looking for PHP blocks and generates the output based on the default internal encoding. In combination with mb_http_output() you can have a source file in one encoding, generating output in a different encoding.
Specify the character encoding for the HTML document:
character_set Specifies the character encoding for the HTML document.
Common values:
UTF-8 - Character encoding for Unicode
ISO-8859-1 - Character encoding for the Latin alphabet
In theory, any character encoding can be used, but no browser understands all of them. The more widely a character encoding is used, the better the chance that a browser will understand it.
To view all available character encodings, look at IANA character sets.
You just replace the below html:
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
Try with special character (ì)
</body>
</html>

Html Special Chars PHP

fm API to get event discription, venue name etc...
Now sometimes I get special chars back like: ' é à , but they show up scrabled.
So how can I display them properly? Also with the descrioption I get html-tags back, but I do want to keep these.
Can someone help me out fot those both cases? The language I'm using is php
Thanks in advance
specify encoding in the header:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
...
encode string when handling the input
$str=utf8_encode($str);
if you are displaying the input back as-is, no encoding is required;
however, if the value is the content of an input or textarea, escape the html characters
<?php echo htmlspecialchars($str); ?>
For Latin characters, use
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
in your section.
you need to be sure about two things, the meta header referring to which enconding you will be using, and the encoding you are using for the text served.
If you are using a utf8 header just be sure to convert the text served to utf8, refer to functions for encoding conversion like : mb_convert_encoding

Some characters become "�" in our webpage

I use PHP to access a database to get a string like this
‘Chloe’ Fashion Show & Dinner
and then I do a printf() to output the string as html, but my webpage shows this:
�Chloe� Fashion Show & Dinner
All contents are English-based, do I miss something in PHP?
Where should I be checking?
Check if your .php file is encoded as UTF-8 without BOM
Check that your connection to the database is UTF-8
Check that you send <meta charset="utf-8"> in your HTML markup in the <head> tag
If your connection to the database is not UTF-8 and you don't want to change it (but I recommend it -> everything UTF-8 is the most secure solution against character rubbish) use utf8_encode($databaseValue) to ensure the encoding of your value is UTF-8.
Make sure that you use:
<meta charset="utf-8">
in the head of your page.
You need to add charset meta tag in 'head' section of html.
Note that the meta tag must appear within the first 1024 bytes of rendered page.
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>

special characters not being displayed correctly in utf-8 encoded file

I have a strange situation.
I am specifying utf-8 in the meta data of my html file:
<!DOCTYPE html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
....
</head>
<body>
<? include("extras.php"); ?>
</body>
</html>
but my speacial characters "ä, ö, å" are being display incorrectly.
Even more strange through is that the same characters used int the included file (hard coded no loaded from php), are being displayed correctly?
can anyone enlighten me as to why this might be?
Encode the special characters, for example, the letter ä you should encode as ä
You can use an HTML encoder/decoder (there are many available online):

or do it programmatically.

How to save Russian characters in a UTF-8 encoded file

OK so I have a PHP file with several strings of text in various languages. For most languages like French or Spanish I just simply type in the characters.
The problem I have is with Russian language characters. The PHP file is encoded in UTF-8, how can I make sure that the Russian characters are both saved correctly and displayed correctly on the output web page... Is it just a case of pasting the text into the PHP file, or is there a way to guarantee the characters will be saved into the file correctly - perhaps converting it into HTML-like notation for example?
Obviously I am assuming the end user will have the correct encoding set in their web browser, I just want to make sure I got it all covered from my end.
I am using Notepad++ on Windows to edit my PHP file.
Thanks!
If you want to tell browsers your encoding, place it inside your <header> tag:
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
Or short version
<meta charset='utf-8'>
That should be pretty enough for Russian characters to be correctly displayed on a webpage.
if your doctype is html declare <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'> but if your doctype is xhtml then declare <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />.Never assume that end-user will act correctly during your designsIf you already have some document, edit your document's meta tag for charset declaration and use notepad++ encoding>convert to UTF-8 without BOM, save your document, safely go on with your multilingual structure from now on.php tag is irrelevant for your question since you don't mention about any database char setting.
There is no difference between Latin and Cyrillic characters in UTF-8. Both are just byte sequences. Configure your server or PHP script to send Content-Type: text/html;charset=utf, and you are rather safe.
Your editor might have problems when the font you are using does not contain Russian characters. Choose another font then.
And please ignore the <meta> element recommendations. You don't need that: it is useless when your HTTP headers are correct, and maybe harmful if they aren’t.
Well you have to check 2 things
To ensure that *.php is an UTF-8 file I use PSPad. If file is not in UTF-8, I save
it like that: http://stepolabs.com/upload/utf-8.png
Then your website must have UTF-8 encoding in <meta> tag;
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
... more about metatagging.
Finally if everything is done well - (format and meta declaration) all should be displayed properly!
