Trouble using symbol for a label.
I am using the dollar sign "$" for a label and it worked fine to add and shows up as label for tasks. Also shows up under list of labels. But, when filtering for just this label I get the following message -
There was an error. Could not understand '@$'.
Please advise as it is helpful to use this and other similar symbols as labels since labels are added in front of tasks and longer ones or multiple ones interrupts the alignment of tasks.
