É vs. E in MySQL database

问题

MySQL thinks É and E are the same and thus throw an exception saying Duplicate entry 'CLEME' for key 'PRIMARY'

MySQL is 5.1.30 and the table uses utf8-unicode-ci and the field is defined as follows:

search_key varchar(120) CHARACTER SET latin1 NOT NULL,

Is there a way to let this field know they are not the same?

Thanks!

回答1:

Change the character set of the field to UTF-8 as well. Also, set the connection character set to UTF-8 when you do the insert.
