Arabic Extended-B

• Ensure UTF-8 encoding and proper font support for the Arabic Extended-B characters used in your UI.
• Implement robust bidirectional (bidi) handling to render RTL text correctly across components.
• Test with diacritics, ligatures, and contextual forms to verify consistent shaping.
• Provide font fallbacks and explicit fallbacks for missing glyphs to avoid blank gaps.
• Document accessibility and language attributes, and test screen readers for correct reading order and pronunciation cues.

Arabic Extended-B covers additional characters used in specialized contexts such as scholarship and historical text. It often appears in typography, scholarly materials, and educational content where precise letter forms and ligatures matter. Practically, you’ll see these glyphs in high-precision displays and font sets that aim to be comprehensive for the Arabic script. For context, this block sits alongside other script extension work to broaden representation while maintaining compatibility with existing Arabic shaping rules.

Typical usage is in typography-focused apps, digital publishing, and educational platforms that present rare or historic forms. Common pitfalls include inconsistent font coverage, broken ligature rules, and unsafe assumptions about glyph availability. Keep an eye on rendering consistency across devices, and verify that related categories like Geometric Shapes, Arrows, Currency Symbols, and Box Drawing remain visually coherent with extended Arabic glyphs.
