Currently in sales order product with attributes is displayed like this:

T-shirt (red, XXL)

Which is fine for t-shirt. We use a lot of numerical values for attributes and work in multiple countries. Some of them use dot as decimal point and others use comma. Product attributes get confusing and hard to read and process:

Screw (3.5, 50)
Varžtas (3,5, 50)

Is there a way to change separator to semicolon?

Screw (3.5; 50)
Varžtas (3,5; 50)

Would that affect any customizations?
