jitsi-meet: Special chars in meeting name break "End meeting for all"

Description:

When a meeting is named with a special character in the name, like a German umlaut, the moderator button “End meeting for all” doesn’t seem to do anything.

Steps to reproduce:

1. Open a meeting with the name büro
2. Make sure you are logged in as a moderator
3. Click the hang up button, then click the “End meeting for all” button

Expected behavior:

The call should be ended for all participants.

Actual behavior:

The button can be clicked but nothing happens afterwards. The button works fine as soon as you have a meeting name without the umlaut e.g. buro instead of büro
