XHTML Symbols
- Below is a quick reference for Logic and Mathematics symbols in XHTML which work on all modern browsers
- These are intended for logical and mathematical articles, or any page requiring special characters not found in the "edit bar"
- Feel free to copy-and-paste (ctrl/cmd-c, ctrl/cmd-v) symbols
- Logic: ¬ ∧ ∨ ∃ ∀ ¬ ∧ ∨ ∃ ∀
- Sets: ∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ ∈ ∉ ∋ ∅ ⊆ ⊇ ⊃ ⊂ ⊄ ∪ ∩ ℵ
- Relations: ≠ ≤ ≥ < > ≡ ≈ ≅ ∝ ≠ ≤ ≥ < > ≡ ≈ ≅ ∝
- Punctuation: · ′ ″ … ‾ ˆ — – · ′ ″ … ‾ ˆ — –
- Numbers: ¼ ½ ¾ ¹ ² ³ ¼ ½ ¾ ¹ ² ³
- Analysis: ∂ ∫ ∑ ∞ ∏ √ ∇ ℘ ℑ ℜ ∂ ∫ ∑ ∞ ∏ √ ∇ ℘ ℑ ℜ
- Arrows: ← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔ ← ↓ → ↑ ↔ ↵ ⇐ ⇓ ⇒ ⇑ ⇔
- Delimiters: ⌈ ⌉ ⌊⌋ ⟨ ⟩ « » ⌈ ⌉ ⌊⌋ ⟨ ⟩ « »
- Binary ops: − × ÷ ⁄ ± ° ⊥ ⊕ ⊗ ∗ − × ÷ ⁄ ± ° ⊥ ⊕ ⊗ ∗
- Misc: † ¦ ∠ ∴ ⋅ ◊ • ♠ ♣ ♥ ♦ † ¦ ∠ ∴ ⋅ ◊ • ♠ ♣ ♥ ♦
- Spacing: thin, width n, width m and non-breakable spaces.      
- Greek: α β γ Α Β Γ etc. α β γ Α Β Γ etc.
- Unicode: ⊢ (for example) gives the character ⊢ with unicode number x22A2 (hexadecimal). Warning: many of the more obscure unicode characters do not yet work on all browsers.
