The easyPoints widget uses the following fonts as it's default.
Japanese: Noto Sans JP
This can be managed in the widget settings.
Default font setting
The font setting is managed with a toggle in the easyPoints Widget app embed setting. When enabled, easyPoints will always load the easyPoints default fonts regardless of the environment. (This may cause a slight load.)
When disabled, easyPoints will not specify the font, and usually will fallback to the the default font of the OS.
We recommend using the easyPoints default font to ensure better styling in all environments, but please make sure to check everything fully when disabling the setting.
