Using special character in field name inside Arcade Expression

[AndrewMurdoch1]

Good Day

I have a field that starts with a % sign %blah,  inside a value expression can I use that value escaped?  Something like:

When($feature.%blah <= 0)

If I leave the % sign, I get an error, and I can't find any information on escaping the % sign, is it possible?

Thanks

Does this work?

When($feature['%blah'] <= 0)

 Possible, it stopped complaining about the % sign when I did that, fields that don't have % sign are rendering properly, but I can't get %blah to show up correctly.
