I think you can pass divider to it, since the options are just passed down to settings and the only thing used in settings is divider. So you can have '|', '*' or anything else passed down and used as dividers. Instead of the default '/'
$.fn.breadcrumb.defaults = {
divider: '/',
keyboard: false
}
Seems to match with the documentation as well: http://jeluard.github.io/bootstrap-breadcrumb/index.html
Options
Name type default description divider string / String used as divider.
