How do I copy a geometry symbols symbol?
Use the Copy button in the table, then verify the Unicode code point if the destination can substitute look-alike characters.
When should I use LaTeX or MathML instead?
Use LaTeX for editable equations and MathML for semantic web mathematics. Plain Unicode is best for short text where the destination preserves the exact code point.
