Glyphs

Named character constants for symbols that are awkward or impossible to type directly in source

Package: @roku-sdk/components/glyphs

The constants are grouped by the property that actually matters at runtime: which font has to supply the character.

1. RokuFont01 characters (the private-use area, plus ● ★ ☆). RokuFont01 is
   the system-wide fallback font in firmware, so these render under a system
   font AND under a custom app-supplied font.
2. RokuUI-Regular symbols. RokuUI-Regular is the default UI font but is not
   in the fallback chain, so these render under a system font but become tofu
   under a custom app-supplied font unless that font supplies them itself.

The practical consequence, verified on device against firmware 15.3.5: if your app ships a custom font, the group that needs care is (2), not (1).

A custom font that defines a codepoint itself always wins — no fallback occurs. A font carrying its own U+E0xx private-use glyphs will render those rather than the Roku icons.
