# Arabic glyphs for UI text (menus, file browser titles). The built-in fonts

# forms — not base letters, or shaped UI text silently drops glyphs.
# Curated for firmware-size budget: core Arabic (Presentation Forms-B,
# incl. the Lam-Alef ligature forms) plus the Farsi/Urdu extra letters'
# Presentation Forms-A blocks, the few characters shaping leaves at their
# base codepoint, Arabic punctuation, and both digit sets. No harakat and
# no Sindhi/Pashto/Kurdish forms — book text gets those from SD-card fonts.
