Display \"]\" in %mn menu

I'm trying to implement a multi language system which would require the ']' character to be embbed in a %mn string. Is there a simple way to do something akin to

winio@('%mn[menu]text]&',cb_func)

winio@('%mn[@]&,','menu]text',cb_func)

or do i have to use the add_menu_item@ method

TIA

I cannot think of a direct way to do this.
