Where does RoundCube use "intl"?

[ZAPnDUSTER]

Hello

I always see that the PHP module "intl" is optional during installation or upgrade checks.

At what point does RoundCube use "intl" and what means optional, i.e. what happens if it is missing?

Thanks

I still find no reference and have no idea, where roundcube uses the PHP module - could anyone please elaborate or explain?

Thanks, I see. So IDNA ASCII (RFC 3490) is the topic.
