How to write Vietnamese in Webflow?

Hi,
My name is Sinh. I had very tired to work with WordPress because of it’s quite slow. I am glad to meet at Webflow. But I don’t know how to write Vietnamese on Webflow. I tried to write it but it was an error.
Example: Tôi Viết Không Được - > To·ôi Vie·êt·ết Kho·ông D·Đuo·ươc·ợc

This is my site: https://preview.webflow.com/preview/sinh-giang?utm_medium=preview_link&utm_source=designer&utm_content=sinh-giang&preview=8c35467d3178e63574f8bf4462a3cc87&mode=preview

Could you please help?

Thanks,

hello, I’m Vietnamese too. Have you solved the issue? It’s very strange that we can’t type Vietnamese in Webflow Designer
