Of course. Greek uses Latin digits. And so on.

We sang this song about a decade ago. Nothing has changed.

We know there would be other combination of scripts would be a problem. We make combination of those scripts and display them in Punycode UNLESS the "language" of the string is configured in the options.

And we sang that one too. What "language" is a string that is two Han characters and some Latin digits?
