And does it work?
I made a test using
{
module: "calendar",
position: "top_left",
maximumEntries: 8,
config: {
calendars: [
{
symbol: "calendar",
url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics"
},
{
symbol: "bell",
url: "https://www.calendarlabs.com/ical-calendar/ics/75/UK_Holidays.ics",
maximumEntries: 4
},
{
symbol: "home",
url: "https://www.calendarlabs.com/ical-calendar/ics/52/Islam_Holidays.ics"
}
],
}
},
and the symbols look OK:
