Are you getting problem after storing into database?

 

by: pramodkrjsrPosted on 2009-09-17 at 21:12:53ID: 25362894

column in the database has to have a character set and collation for utf8.  I.e.
CHARACTER SET utf8 COLLATE utf8_general_ci
 
2.  The request before storing to the database has to be handled as UTF-8.  I.e. needs a
request.setCharacterEncoding("UTF-8");
line before any submitted parameters are read.  This was the vital missing piece of the
jigsaw for me.
 
3.  The response also needs to be handled as UTF-8.  I.e. needs a
response.setContentType("text/html; charset=UTF-8");
line in all files handling the response.  Not totally sure if this is required as one file
worked without it.
 
4.  The character set and encoding need to be set on the database URL in the web.xml.
E.g.
<url>jdbc:mysql://localhost:3306/DATABASENAME?useUnicode=true&amp;characterEncoding=UTF8</
url>

I'm not sure wheter I'm right.  For create table I write like below :

CREATE TABLE utf8test (
name varchar(25),
descr varchar(25)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

But when I view the database that contain japanese character, it show like below:
+-------------------------+-----------------------+
| name                          | descr                      |
+-------------------------+------------------------+
 | &#26908;                 | &#26908;                  |
| &#26053;&#34892;   | &#26053;&#34892;  |
+-------------------------+------------------------+

It ok, When you view it in jsp, then it will display correct.

 

by: sitijaafarPosted on 2009-09-17 at 22:48:42ID: 25363160

I already set character_set_client="utf8";
and
 set character_set_server="utf8";

 

by: sitijaafarPosted on 2009-09-17 at 22:56:09ID: 25363182

So, that means for one japanase character it will store in database as 8 characters because it will store it as for example &#26908;  .  But how to store the japanase character as a one character.  Actually,is it possible?

Can we know what Web Server / Servlet Container you're using?

You may need to configure the encoding charset on your config file, etc.

I'm using apache-tomcat. So, how to configure the encoding charset?

         HI!

In MySQL you should check your tables/database to see what character-set/collation is set on the table/database using
these commands
http://dev.mysql.com/doc/refman/5.0/en/show-create-table.html
http://dev.mysql.com/doc/refman/5.0/en/show-character-set.html
http://dev.mysql.com/doc/refman/5.0/en/show-collation.html

To change use ALTER TABLE/ALTER DATABASE commands
http://dev.mysql.com/doc/refman/5.0/en/alter-database.html

http://dev.mysql.com/doc/refman/5.0/en/alter-table.html

NOTE that "SET CHARACTER SET and SET NAMES assign values to character set and collation variables associated with the connection to the server." (see manual http://dev.mysql.com/doc/refman/5.0/en/set-option.html ) the tables/database are maybe configured differently and the only way to change that is to
use ALTER DATABASE/TABLE.

Regards,
    Tomas Helgi

You need see this:
http://wiki.apache.org/tomcat/FAQ/CharacterEncoding

And you may get a try by executing this statement, before your Select statement:

SET NAMES utf8;
