Unicode includes over 2,000 math-related characters — from simple superscripts and fractions to full Greek alphabets and advanced calculus operators.

How to Use Unicode in Any Environment (Quick Rules)

Examples (using U+2212 MINUS SIGN −):

HTML (safe everywhere) Decimal: − Hex: −
CSS \2212 (1–6 hex digits; add a space if next char is alphanumeric)
JavaScript (ES6+) \u{2212}
JavaScript / JSON (legacy) \u2212
Python \u2212 or \U00002212 (always valid)
Regex (PCRE) \x{2212}
SQL (PostgreSQL) U&'\2212'
SQL (MySQL / SQL Server / SQLite) NCHAR(8722)
Shell (ANSI‑C quoting) $'\u2212'

Syntax Form	Systems
`&#xHHHH;` / `&#D;`	HTML, XML, SVG, SGML
`\HHHH`	CSS (1–6 digits, space to terminate)
`\u{HHHH}`	JS ES6+, PHP, Ruby, Rust, Swift, PowerShell
