Symbol, Math (Sm)

• Test symbol rendering across popular fonts to ensure coverage for common and rare Sm code points.
• Use normalization aware processing to avoid misinterpretation when comparing or sorting symbols.
• Document accessibility impact, providing readable names or alt text for screen readers.
• Group related symbols logically in UI, with clear visual cues to distinguish math from other symbol types.
• Refer to related blocks for broader context and consistency—Arrows Block and Geometric Shapes Block.

Symbol, Math (Sm) covers all code points classified as Sm. These are symbols that do not render as letters but create meaningful math or notation. In practice, they appear in formulas, operators, and annotations, often in combination with digits or letters.

Typical usage involves careful font and rendering choices, especially for math-heavy interfaces. Be mindful of variation across platforms and ensure that input, storage, and display remain consistent. A high-level historical pattern is that symbol blocks were shaped to support textual math notation without introducing letter-like behavior; modern systems focus on interoperability and accessibility to avoid ambiguity.
