Magent2 - Quote and Order SKU need to change delimit from "-" to "|"

[g_jagadeesan]

Hi,

I am adding a free product through the customizable option section in the Product admin page.

For Ex:

Main Product SKU: A-123

Free Product SKU: Free-987

When user placed an order the above Product with free product, In quote_items table and sales_items table the SKU column concatenate like this A-123-Free-987.

In this scenario, Magento 2 using delimit as "-". I want to change the delimit from "-" to "|" in both Cart table and order table while user placing the order. Kindly let me know where I need to change the delimit of the above scenario.

Thanks
