How to make lorecontains can detect string with underscore?

[cgw2023]

my minecraft user name is anzai__chiyomi
An item's lore contains my name, I try to use %checkitem_lorecontains:anzai__chiyomi%, it does not work, but it works when I do %checkitem_lorecontains:anzai%.

I am trying to make automated script to check player holding item with their name in lore, but the above checkitem %checkitem_lorecontains:{player_name}% will broke if name contains underscore, how to solve this?
