How to escape a . (dot) in a PropertyPath in code behind

[amtopel]

Is it possible to escape a . (dot) within a PropertyPath when creating a Binding in code behind? I've come across some sources suggesting you can use square brackets, or possibly \u2024, but it appears those solutions might work only in XAML. I have yet to find an approach that works in code behind. My current solution is to substitute in underscores for the dots, but I'm wondering if there's a better way. Thanks for any info or guidance.
