How to pass a python string containing @ character character in a MEL.Eval function

Question

Im trying to pass a path containing a @ special character in a FBX export mel command using the mel python package.

fullPath = "E:\SomeFolder\[email protected]"
mel.eval('FBXExport -f "{}" -s'.format(fullPath))

Im getting this error

RuntimeError: Error occurred during execution of MEL script
# Line 1.14: Syntax error # 

I've tried repr with Python but it seems to be a MEL sided error.

mel.eval('FBXExport -f "{}" -s'.format(repr(fullPath)))
