Panels can be created with special characters, but apparently they cannot be inserted in the columns.
- Go to Panels.Home and create a panel with the following name:
- Go to the administration -> Panels -> Panels List and drag and drop the panel you created in the right column
- Save the layout
- Go back to Administration -> Panels by the menu to reload the page
- The panel is still on the right column
- The "Panels displayed on the right" text field from Panel administration shows it with its full name
- The panel is not displayed anymore
- The "Panels displayed on the right" text field shows
only instead of the full name: looks like the reference is truncated before the first symbol.
