Tracks/waypoins folders manager and non-alphanumeric characters

[Fritzle]

Tracks and/or waypoints folders names created in the past may contain non-alphanumeric characters (spaces, dots, underscores, etc.), e.g. tracks folder name "My favorite tracks", and are still accessible. But within recent version 10.6.3 as well as within some versions before, unfortunately keyboard input of those characters is ignored when creating a new tracks/waypoints folder. Only alphanumeric characters are accepted. Bug or feature?
