Identify the app-development scope and SDK
Roku’s RSG 2.0 component type documentation distinguishes system-font specifications from custom font paths. This guide covers developer-controlled app text using that documented SDK. It does not identify the Roku wordmark or offer a device-wide menu-font changer. Begin by recording the SDK and component you are using so an example for a different interface is not mistaken for a compatible instruction.
Choose a system role or a packaged custom resource
The documentation provides case-sensitive system references such as font:MediumSystemFont and describes system-font behavior for localization and accessibility preferences. It also documents custom TrueType or OpenType paths such as pkg:/fonts/MyFont.ttf. Choose the route deliberately: a built-in role avoids bundling a custom face, while a file path requires the actual authorized resource in the app package. Keep the selected role or exact file path with the component’s text specification.
Compare the same label before testing a complete screen
The official RSG 2.0 Showcase catalog includes system-versus-custom comparisons and a Font example with packaged TTF resources. Start with one title, one episode number and one longer action label. Check wrapping, clipping and alignment in the target app rather than relying on a browser specimen alone. Keep any screen-wide styling change separate from the control proof. The homepage’s Unicode text styles change characters; they do not select a Roku SDK font role, package a custom font or change the device’s global interface.
Your questions, answered.
Does this change the font of every Roku menu?
No. This workflow concerns text controlled by a developer’s RSG 2.0 app. It is not a device-wide font-setting tool.
Can a copied text style replace a packaged custom font?
No. The app needs the actual resource and correct font specification. Copying characters does not provide that font file or role.
