+Unicode
+-------
+
+MySQLdb will accommodate Python ``unicode`` objects if the
+``use_unicode=1`` parameter, or the ``charset`` parameter,
+is passed as a connection argument.
+
+Without this setting, many MySQL server installations default to
+a ``latin1`` encoding for client connections, which has the effect
+of all data being converted into ``latin1``, even if you have ``utf8``
+or another character set configured on your tables
+and columns.  With versions 4.1 and higher, you can change the connection
+character set either through server configuration or by including the
+``charset`` parameter.  The ``charset``
+parameter as received by MySQL-Python also has the side-effect of
+enabling ``use_unicode=1``::
+
+    # set client encoding to utf8; all strings come back as unicode
+    create_engine('mysql+mysqldb:///mydb?charset=utf8')
+
+Manually configuring ``use_unicode=0`` will cause MySQL-python to
+return encoded strings::
+
+    # set client encoding to utf8; all strings come back as utf8 str
+    create_engine('mysql+mysqldb:///mydb?charset=utf8&use_unicode=0')
+
+Known Issues
+-------------
+
+MySQL-python version 1.2.2 has a serious memory leak related
+to unicode conversion, a feature which is disabled via ``use_unicode=0``.
+It is strongly advised to use the latest version of MySQL-Python.
