Resolution Note (2020.1.X):
This problem comes from that WebGL builds do not embed .NET resources by default, and the Unicode resources are needed for the case insensitive string functions to work. You can embed them via:
https://docs.unity3d.com/Manual/webgl-embeddedresources.html
We will investigate whether we should embed these resources by default, or at least make the option more accessible and clearer to associate with String/Unicode issues.
