jsp insert into database no utf-8 - mysql

I've got web-app (jsp) which is using database (mysql). I've put some data into database to test is it work to show in jsp what's in database There was issue with utf-8 characters (polish letters) but i fixed it by adding <parameter-encoding default-charset="UTF-8" /> into glasfish-web.xml. But i still got problem with putting data into database from form. In database instead of polish character i got "?????". I've tried many thinks and nothing Dont reallu now where to look to fixit

ok problem solved I'll put answer for other people having same problem
In jsp where i start my database connection for url="jdbc:mysql://localhost/databasename i changed it into
url="jdbc:mysql://localhost/databasename?useUnicode=true&characterEncoding=UTF-8"
and now everything in database looks like it shoudl

Problem you have faced is that java has escaped the UTF-8 character sequence.
you can use StringEscapeUtils provided by java in order to escape any characters which become ??? or anything else.
try this :
str = org.apache.commons.lang.StringEscapeUtils.unescapeJava(str);
From java

phpmyadmin does not show non-English characters correctly

I'm using phpmyadmin for many years but never tried to solve this problem. My database collation is utf8_persian_ci and the table also has the same collation.
While I open phpmyadmin, it doesn't show characters correctly. I see something like برنامه.
In local host I solved this problem by commenting this line:
PMA_DBI_query("SET CHARACTER SET 'utf8';", $link, PMA_DBI_QUERY_STORE);
in /usr/share/phpmyadmin/libraries/database_interface.lib.php but I don't have persmission to do such action in a shared host.
What should I do about this?
NOTE:
The problem is only about PhpMyAdmin. I can see my data correctly when I retrieve them using PHP
To convert your "garbage" data, you need to find out in which character set the data is encoded, then code a PHP application that will read the rows, convert the columns with a function like iconv() (http://www.php.net/manual/en/function.iconv.php) and update the rows.
Hint: your PHP application that displays your data correctly, probably generates a page using a certain character set. So use this character set as the input charset of the iconv() function.

how to show special characters on my site?

I am currently working on a site that connects a DB and bring the information, some of this information has special characteres because is in polish languague, for example, in the database I have this one ę and I get e printed at my web,I already added the meta
<meta charset="ISO-8859-2">
but doesnt work, only if I write & #281; which is not pract and needs a lot of work, my question is if somebody did this , get the character, like ę, and print it just like that?
Thanks.
Make sure that:
the data really is in ISO-8859-2
the data isn't be corrupted by the configuration of the database
the HTTP headers aren't claiming the data is encoded a different way
whatever you are using to pull the data out of the database isn't transcoding it
You should also ditch ISO-8859-2 (as it is very legacy) and move to UTF-8.
Use a Unicode entity. &#xxxx; where xxxx is the Unicode value for the character.

Saving special characters to MySQL database

I am currently having an issue saving special characters (® & ©) to a mySQL database.
On a local stack (local to my development machine) the operation runs smoothly and what is entered in the front-end gets saved as what is expected.
With the same front-end code on the centralised server when saving to the DB the character is proceeded with other characters it is saved as ®.
This isn't an issue when viewing the record on the front-end as it reverses what it does and displays correctly.
The issue comes from another separate system which utilises the same database and doesn't do any alteration so appears as the ® instead of simply ®.
The reason for my confusion is that it seems to work as required on my local stack but not on the centralised server.
I am looking for ideas as to what to look for which might be causing this on the servers configuration compared to my local.
Thanks in advance

#Pranav Hosangadi (thanks) covers three areas to check for consistency of encoding. The following solution adds to that. It may also be worth considering (a variation of) #Soaice Mircea's answer (thanks also) for some scenarios whereby this answer doesn't fix the problem although this wasn't required when I was able to reproduce and find a solution to your problem. #Pranav's line of thinking seems to be successful for this problem as it's about consistency of using one character set everywhere rather than a particular one.
five things to do:
ensure database charset and tables use same charset throughout, inspect this in phpmyadmin for example, note and this charset for use below
use php header() function with database charset e.g.:
header('Content-Type: text/html; charset=latin1_swedish_ci');
insert meta tag in html header e.g.:
<meta http-equiv="content-type"
content="text/html;charset=latin1_swedish_ci">
add charset-accept in form tag
<form action=\"testsubmit.php\" method=\"post\" accept-charset=\"latin1_swedish_ci\">
set charset of mysql connection e.g.:
$con = mysql_connect("localhost","test","test");
mysql_set_charset ( "latin1_swedish_ci", $con );
after you select the DB in php code add this:
mysql_query("set names 'utf8'");
also check if the column where you store the text has utf8 encoding.

MySQL UTF8 Problem

I have a strange UTF8 encoding problem, which I don't understand.
If a friend of mine fills out a form on my webpage, then all german "umlauts" (ä,ü,ö) are displayed in strange chars in my database. When I do the same, they are displayed normally, how it should be. Everything is set to utf8_general_ci, so it should work. But it doesn't, when my friend fills out the form.
Has anyone a suggestion for me?
Thanks!
Even though all tables are UTF-8, the database connection might be using latin-1. What output do you get with SHOW VARIABLES LIKE '%character%'; in MySQL? Any signs of latin-1 there? If so, adjust your charset settings in the MySQL configuration file.
You haven't specified the language you write your app in, and it seems to be connection-based problem. You must manually set connection encoding, f.g. in JDBC, by appending on the end of connection string "?characterEncoding=utf8"
Run SET NAMES utf8 on mysql right after connection

Can't find out where my Ruby 1.9 string encoding is getting messed up

Somewhere along the line from the DB to the application, this:
sauté
is getting turned into this:

I'm using Ramaze + Rack + MySQL. I've got a force_encoding plugin set up, so the encoding on the string is UTF-8. If I view the record in the database shell, it's looks fine. The default charset on the table is utf8, and the field itself is "text". The encoding on my database connection is utf8. Also, on my Macbook, everything works great. It's on my Ubuntu server that it's getting mangled. I'm hoping that someone may recognize this and tell me that it's unicode getting turned to ASCII, then back, or something like that.
Most likely your locale differs.
Run the locale command on both and see what's the difference.
I assume you see an issue when you get results back from MySQL, which is a common issue with 1.9 according to google results: http://www.google.com/search?q=mysql+ruby+1.9+encoding.
