SQL unique varchar case sensitivity question

Question

I\'m trying to populate a SQL table with a list of words. The table itself it pretty simple:

CREATE TABLE WORDS(
  ID BIGINT AUTO_INCREMENT, 
  WORD VARCHAR(

Looks like mysql is case insensitive by default:

You probably need to create the column with a case sensitive collation (e.g. utf8_bin):

CREATE TABLE WORDS (
    ID BIGINT AUTO_INCREMENT, 
    WORD VARCHAR(128) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL UNIQUE, 
    PRIMARY KEY(ID)
);
