Setting MySQL to Default to Unicode

When running unit tests in Django, I was getting a strange MySQL failure when attempting to insert non-ASCII Unicode characters into the database, for example:

[code light=”true”]
Warning: Incorrect string value: ‘\xE2\x89\xA5 %’ for column ‘value’ at row 1

What is happening is that Django creates a new schema from scratch for testing. This new schema picks up the MySQL defaults. All my test tables ended up with Latin-1 encoding instead of UTF-8 encoding.

I needed to change mysqld to default to unicode internally so Django will run unit tests involving correctly.

In /etc/my.cnf I added the following:

[code lang=”c” light=”true”]


collation-server = utf8_unicode_ci
init-connect=’SET NAMES utf8′
character-set-server = utf8
