how to use a class with special characters in class name?

I am trying to use Matlab to control a linear stage from Thorlabs. The old codes (Driver for Thorlabs motorized stages - File Exchange - MATLAB Central (mathworks.com)) no longer work, then I played a bit and found the cause being a value in an enumerate structure (in c++) was not accessible, though Matlab knows correctly that the value belongs to an enumerate class. Interestingly, it was because there was a plus sign "+" in the class name, returned by Matlab (in the real .dll, I don't know if the original class named in that way). So, is there a way to get access to a member of such kind of classes that have a special character in their names?

The following is some output during the debug process.

K>> class(h.currentDeviceSettingsNET.Rotation.RotationDirection)

ans =

    'Thorlabs.MotionControl.GenericMotorCLI.Settings.RotationSettings+RotationDirections'

K>> enumeration Thorlabs.MotionControl.GenericMotorCLI.Settings.RotationSettings+RotationDirections

Enumeration members for class 'Thorlabs.MotionControl.GenericMotorCLI.Settings.RotationSettings+RotationDirections':

    Quickest
    Forwards
    Reverse

K>> Thorlabs.MotionControl.GenericMotorCLI.Settings.RotationSettings+RotationDirections.Forwards
Unable to resolve the name 'RotationDirections.Forwards'.

You could try

Thorlabs.MotionControl.GenericMotorCLI.Settings.('RotationSettings+RotationDirections').Forwards

It might work, depending on the internal implementation.

Thank you. It worked!
