Data Studio cannot handle non-Latin scripts
I send a value from Android through Google Analytics as a Dimension, and since Dimensions are handled as strings in GA, this means that the string will be sent in whatever the locale script is. That is a problem in itself for many reasons, but in Data Studio, there is the addition problem that when I try to configure Data Sources to handle this value as a number, it only works for strings sent in Latin Scripts; all other scripts results in a NaN error value, which is obviously not very useful.
While I guess that in theory this can be fixed on the device side, that will not help me with devices which will not be updated or with existing data. So this should be fixed in Data Studio.
