Hi,
UTF-8 is 8 bit code.
Unicode ist 16 and it includes all the chars we know today over all the
world.

The above is *wrong*.

Unicode is a character set, with a 21-bit character space at the most recent reckoning.

UTF-8 is an *encoding* of Unicode, in which characters are encoded in groups of 8-bit bytes, with different characters taking up 1, 2, or 3 bytes. UTF-8 can indeed encode every single Unicode character.

UTF-16 is similarly an ancoding of Unicode, in which characters are encoded in groups of 16 bits each, with different characters taking up 1 or 2 such 16-bit groups each.

If you want to write arabic , ascii, german, French and etc... in your db.
Use unicode. the UTF-8 do not include all these chars in one

False: UTF-8 can be used to encode any and all Unicode characters. Thus, if your database stores strings in UTF-8, then it can handle the full gamut of characters and languages that Unicode handles. If you tend to store many strings that contain characters that would be encoded using 3 bytes using UTF-8 but would only use one 16-bit group if encoded with UTF-16, then using UTF-16 rather than UTF-8 may save you space, but that's the only real difference.


see this for more information about :
http://www.columbia.edu/kermit/csettables.html

Attention that you can set the encoding  in the DB, java as well as the
brwoser.
and all must fit together for good results.

UTF-8 and UTF-16 are excellent candidates for this,

Sako.
