Korean font style application problem

Hello, we are a Korean startup company developing web software with Webflow.

While developing the page, I noticed that our Korean custom fonts were not being applied in Windows 10 and Chrome environments.

However, I confirmed that both Korean and English are applied only in a Mac, Safari environment.

Is there a reason why only Korean is not supported on Windows?

Or, is it possible to apply style localization only through an enterprise-level subscription? If so, I would like to be informed of the price for this part.

If not, please tell me in detail how to solve it.

thank you
