Special character in fbx animation names

I have created a model, rigged it with bones, and created some bone actions (animations) then i exported the model along with the animations into an fbx format for use with Unity, but the Blender added special character | into the animation names, which makes the animations unusable in the Unity. The names of the animations look like this “Armature|ActionName”. I need some way to set the blender to NOT use | in the animation names. It doesn’t matter which way the animations are named, but there can’t be any special characters like | in their names.

Thanks in advance for any advice.
