All possibilities of uppercase and lowercase

I have a task to do here at work which I must test, and I'd like to know if there is a way to show all possibilities of uppercase and lowercase letters within the same word, using some script or any other tool, example:

Word I need to test:

en-emea

All possibilities of uppercase and lowercase:

en-emea
En-Emea
en-eMea
eN-emEa
en-emeA
EN-EMea
en-EmEa
...

It could be any programming language, I just need the output text.
