Mysql and special chars on keys

Question

In mysql with "latin1_swedish_ci" collation these records:

   INSERT INTO test VALUES ('è');
   INSERT INTO test VALUES ('e');

are the same... If this varchar colum is a primary index and I try to inser these values I get a duplicate primary key error. Is it possibile to change this behaviour?

thanks

Which version of MySQL are you using? It could be a unicode problem

MySQL VARCHAR Lengths and UTF-8

on the other hand it might be your character_set_client http://stackoverflow.com/questions/12260386/change-variable-in-mysql – KeepCalmAndCarryOn Jun 25 '13 at 10:50

you can insert ascii code to db as the following

INSERT INTO test VALUES ('232');
INSERT INTO test VALUES ('101');

Then you can read them and in php use chr function to get character.
