I'm using phpMyAdmin version 4.4.4 with MySQL 5.6 (charset is set to UTF-8 Unicode). The table in question has the collation set to utf8-general-ci and all fields are also set to utf8-general-ci collation as well. My php.ini file has default_charset = "UTF-8".
Despite all the UTF-8 settings for all three applications, unicode characters appear garbled when viewing a table within phpMyAdmin. So, instead of seeing ...
Søren
... in phpMyAdmin I see ...
Søren
Even though it displays garbled in phpMyAdmin, it displays correctly on the website. The only problem is with phpMyAdmin.
If I attempt to Insert a new record using phpMyAdmin and enter Søren in a text field, it displays like this within phpMyAdmin...
Søren
Which looks correct there, but, on the web page, it displays like this...
S�ren
The ø character is replaced with a question mark inside a black diamond instead of displaying the proper unicode character on the website.
What the heck is going on? How do I make phpMyAdmin display and insert the unicode characters properly into the table without mangling them? Thanks!
My php.ini file has default_charset = "UTF-8".
That only affects the charset used for some PHP built-in functions like htmlentities.
MySQL uses its own charset to decode stuff you send it. This can be set using $mysqli->set_charset('utf8') for mysqli, or mysql_set_charset('utf8') for the deprecated mysql module, or using charset=utf8 in the connection string in PDO.

My MySQL database contains some Chinese symbols and such (non-ASCII symbols). When I view them in PHPMyAdmin, they look garbled. However, if I display them on my website with PHP using the regular mysqli API, it looks fine so I assume the data is uploaded/stored properly in the database, so maybe the server connection collation is incorrect.
My PHP code for opening the database connection is:
function openConnection(): mysqli
{
$databaseHost = "localhost";
$databaseUser = "root";
$databasePassword = '';
$databaseName = "my-database-name";
$connection = new mysqli($databaseHost, $databaseUser,
$databasePassword, $databaseName);
if ($connection->connect_error) {
die("Connection failed: " . $connection->connect_error);
}
return $connection;
}
My PHPMyAdmin server connection collation is the default utf8mb4_unicode_ci which seems to be reasonable as well. My tables are also created with the default utf8mb4_general_ci. Shouldn't that work fine for any input users might make?
Calling $connection->get_charset() in PHP also returns the correct charset:
If I export the database data in MyPHPAdmin, the export is also garbled in Notepad++, I made sure to view it with UTF-8 encoding. If I import the garbled export again, the database will show the data as garbled once more and on the website the data now also shows as garbled. In this case, an actually corrupted export happened.
How can I solve this encoding problem? Clearly PHP can handle UTF-8 properly, my Apache web server is also serving UTF-8 and my database is configured seemingly correctly as well but there is an issue with PHPMyAdmin or the database/database table collation.
It looks like the issue was entirely elsewhere since I'm supplying data to PHP with C++ code. The C++ code uses the nlohmann JSON libary to build the data submitted to the PHP script. The issue was my inability to specifically encode std::strings to UTF-8 like described here when putting data into a C++ JSON object. With that said, everything is now working as expected.
⚈ If using mysqli, do $mysqli_obj->set_charset('utf8mb4');
⚈ If using PDO do somethin like $db = new PDO('dblib:host=host;dbname=db;charset=utf8mb4', $user, $pwd);
⚈ Alternatively, execute SET NAMES utf8mb4
Any of these will say that the bytes in the client are UTF-8 encoded. Conversion, if necessary, will occur between the client and the database if the column definition is something other than utf8mb4.
More notes on PHP: http://mysql.rjweb.org/doc.php/charcoll#php
If you have specific garbling, see Trouble with UTF-8 characters; what I see is not what I stored
If you suspect the data being fed from PHP to Notepad, dump a few Chinese characters in hex and shown to us. I would expect every 4th character to be hex F0 or every 3rd to be between E3 and EA. (These are the first byte for 4-char and 3-char UTF-8 encoding of Chinese characters.)
Does Notepad properly handle UTF-8, or does it need a setting?
If you are in the "cmd" in Windows, you may need chcp 65001; see http://mysql.rjweb.org/doc.php/charcoll#entering_accents_in_cmd That way, more non-English characters will display correctly.
I have a database in PhpMyAdmin where it's caracter set is UTF-8 which doesn't display correctly (it contains weird symbols).
I tried following this solution here , but I still have the same problem.
Also I tried this solution too: solution 2 but this didn't work .
The last thing I did is export the database in to an SQL file then changing it with Notpad++ to encode UTF-8 and then importing this SQL file in to the database again, but nothing changed; the gebberish characters still exist.
I am using:
PhpMyAdmin ( wamp server version : 5.7.24 - MySQL)
Database caracter set : UTF-8 Unicode (utf8)
The colloation proprety in PhpMyAdmin : utf8_general_ci
When I insert values in database like words in french (" é ") it works, but the old existing values returns just symbols and weird things like contr├┤le
My application is coded using PHP and I start every connection to database with :
$db->exec("set names utf8");
I hope someone can guide me to how to solve this probelm I will appreciate it very much .
I'm new to MySQL and i'm working on it through phpMyAdmin.
My problem is that i have imported some tables with (.sql) extension into a database with: UTF8_general_ci format and it contains some Arabic or Persian characters. However, when i export these data into an Excel file, they appear as the following:
The original value: أحمد الكمالي
The exported value: Ø£Øمد  الكمالي
I have searched and looked for this issue and tried to solve it by making the output and the server connection with the same format UTF8_general_ci. But, for some reason which i don't know, the phpMyAdmin doesn't allow me to change to the same format, it forces me to chose this: UTF8mb4_general_ci
Anyway, when i export the data, i'm making sure that the format is in UTF8 but it still appears like that.
How can i solve it or fix it?

I found easier way that you can rebuild excel file with correct characters.
Export your data from MySQL normally in CSV format.
Open new Excel and go to Data tab.
Select "From Text".if you not find this it is under "Get External Data".
Select your file.
Change file origin to Unicode(UTF-8) and select next.("Delimited" checked by default)
Select Comma delimiter and press finish.
you will see your language characters correctly.See more
Mojibake. Probably...
The bytes you have in the client are correctly encoded in utf8mb4 (good).
You connected with SET NAMES latin1 (or set_charset('latin1') or ...), probably by default. (It should have been utf8mb4.)
The column in the tables may or may not have been CHARACTER SET utf8mb4, but it should have been that.
(utf8 and utf8mb4 work equally well for Arabic/Persian.)
Please provide more details if this explanation does not suffice.
I wrote a short script which simply inserts Unicode characters into a MySQL database. It looks like this:
mysql_connect('localhost', 'root', '*') or die(mysql_error());
mysql_select_db('test') or die(mysql_error());
mysql_query("INSERT INTO thetable (thefield) VALUES ('äöüß')") or die(mysql_error());
I generated the script using Notepad++ and it's UTF-8 encoded without BOM.
The database and the table have a utf8_general_ci collation. When I look at the data using PhpMyAdmin then the charset seems to be broken. The characters are not displayed correctly:
äöüß
When I receive the data back in my script then the charset seems to be okay. I dumped it with the right header (header('Content-Type: text/html; charset=utf-8')) and everything looks right.
When I insert data into the table using PhpMyAdmin again, then it is displayed correctly inside PhpMyAdmin, but as soon as I dump it from my Demo script, then the charset is broken again.
I have no idea what the reason could be. The database's charset, the HTTP header and the encoding of the script are consistent and I don't doubt that PhpMyAdmin is working correctly. So where else could I look for the problem?
Your getting 2 characters for every one in the original, so its reading it as standard ASCII instead of unicode. you probably need to specify the character set the MySQL Connection is using when you connect.
I'm on my cell, but if u post your DB connect code I can show you how when I get to a computer
Edit - see PHP PDO: charset, set names?
I use MySQL 5.1 and loaded from a UTF-8 decoded txt-file about 2.7 mil lines into a table which itself is declared as utf8_unicode_ci and as well all char-fields are declared as utf8_unicode_ci, using LOAD DATA INFILE...
In the database itself the characters all seem to be correct, everything looks nice. However, when I print them using php, the characters show up as ???, although I use utf-8 declaration in the HTML head:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
...
In another table (using utf-8), where I inserted text from a submitted form, the characters appear strangely in the database, but are shown correctly again, when I print them using SELECT....
So, I was wondering: what is wrong? Are UTF-8 chars shown correctly in the database or strangely but when you SELECT them again they are OK? Or where is the problem (when loading the file into the db, in the HTML or somewhere in between)??
Thank you very much for any hint or suggestion! :)
Note: MySQL's utf8 charset is limited, it only supports Unicode characters in the BMP that take up no more than three bytes. You should be using utf8mb4 instead.
Make sure you send the SET NAMES utf8 SET NAMES utf8mb4 command to MySQL after connecting, before running any MySQL queries.
Make sure your page is actually rendered as utf-8 (if there's an HTTP header Content-Type: text/html;charset=iso-8859-1, browsers disagree about which should win).
Read this article: Handling Unicode Front To Back In A Web App (but remember to replace utf8 with utf8mb4 where MySQL is concerned).
If phpMyAdmin displays your entered data as correct Unicode text, then my bet is that you are not doing SET NAMES utf8 after connecting.
Try use such code after connecting to DataBase, but befor you recieve data
$db->query('set character_set_client=utf8');
$db->query('set character_set_connection=utf8');
$db->query('set character_set_results=utf8');
$db->query('set character_set_server=utf8');
