Greek Letters in Writing & Formulas
Character identity matters even when two glyphs look nearly identical.
Greek and Latin are different scripts
Greek Α and Latin A can look alike, but their codes differ: U+0391 versus U+0041. Use the intended script in a word, variable or label.
Choose sigma or summation
Σ is the capital letter sigma. ∑ is a summation operator. A mathematics editor may size and position the operator differently from the letter.
Check mu and the micro sign
μ is GREEK SMALL LETTER MU, U+03BC. µ is MICRO SIGN, U+00B5. They are separate characters even when a font draws them the same way.
Use final sigma for its context
The final sigma ς is different from σ. This collection lists it separately so you can choose the form needed in a Greek word.
