Hello,
We're using a commercial font called "Campton" in our RevenueCat paywall. We're occasionally seeing characters in certain languages render incorrectly (please see the attached screenshot).
One thing we found odd is that if we change the device's system language to that language and reopen the paywall, the characters that were previously broken now display correctly.
For example, with the device language set to Korean, some characters were broken when viewing the Vietnamese paywall. After changing the device language to Vietnamese, those same characters rendered properly.
Because of this, we'd like to understand how fonts are applied to paywalls. For instance, when the configured font doesn't support certain characters, is there any fallback logic — such as falling back to the system font?
Thanks in advance for your help.
