> **Note:**
>
> Regular expressions use **ECMAScript** format for the supported properties. However, the Unity Editor and runtime use different regex engines that both support **ECMAScript**. The Unity Editor uses the `.NET` regular expression engine with the [RegexOptions.ECMAScript](https://learn.microsoft.com/en-us/dotnet/api/system.text.regularexpressions.regexoptions?view=net-10.0#system-text-regularexpressions-regexoptions-ecmascript) flag, while the runtime uses the [C++ modified ECMAScript](https://en.cppreference.com/w/cpp/regex/ecmascript.html) by default. The Editor validation confirms valid regular expression syntax, but the expression might produce different filtering behavior between the Editor and runtime. To verify runtime behavior, test the device filtering on actual devices.
