Uppercase locale string

[omsoft]

Is it possible to generate globalize queries with an uppercase locale? For instance should be:

SELECT * FROM `event_translations` WHERE (`event_translations`.`locale` IN ('IT')) AND (`event_translations`.event_id = 1406)

intead of:

SELECT * FROM `event_translations` WHERE (`event_translations`.`locale` IN ('it')) AND (`event_translations`.event_id = 1406)

Thanks in advance
