Hi Cesium Team,
From some versions of Cesium i hava a problem with RegExp("[א-ת-ۿݐ-ݿࢠ-ࣿ]")
and also with sandbox, in every new version i need to change Cesium.js file to fix this issues and then it work fine. I change:
RegExp("[א-ת-ۿݐ-ݿࢠ-ࣿ]") --> RegExp("/א-ת-ۿݐ-ݿࢠ-ࣿ/"),
setAttribute("sandbox","allow-same-origin allow-popups allow-forms") -->
setAttribute("sandbox","allow-same-origin allow-popups allow-forms allow-scripts")
I think this problem occurs because my region is in Eastern Europe
Best Regards
