Marten Lehmann napsal(a):
Hello,
I have a table like this:
CREATE TABLE `places` (
`name` varchar(256) collate utf8_unicode_ci NOT NULL,
PRIMARY KEY (`name`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci |
Then I want to insert two values:
pjöngjang.com and
pjongjang.com
But on the second record I get this message:
DBD::mysql::st execute failed: Duplicate entry 'pjongjang' for key 1
Whats wrong with it? The character set and collation set is defined as
utf8, so mysql should see a difference between "ö" and "o".
Regards
Marten
It's not problem of charset but collation. Try to change collation to
utf8_bin if it's possible. "ö" and "o" are of course stored as two
different chars in utf8 but collation gives them weight for correct
ordering and probably in utf8_unicode_ci collation they have same weight.
HTH,
Dusan
