Language change in WinCC Comfort v11 SP2

I want to change the text language inside the screens from English to Viatnamese with Viatnamese font. The customer is very specific that the language and the texts written should be in the Viatnamese. Can this be done? If so, how?

I see that, in the project language, the Viatnamese language is available but to enter the text and form a text library, the Viatnamese font is not there.

Attached is the screenshot of how the customer wants the text in the screen.

How do I do this?

Thanks,

Thanks for the reply. We have already set the language in the Project settings and Runtime settings.

But the Viatnamese font is not available. When I copy some random Viatnamese font from internet and paste it in the text library, it displays it as boxes. How do I get the font? Do I have to use Asia version of the software?

Thanks,
