Znaki specjalne / litery greckie

Znaki specjalne możemy zapisać używając konstrukcji z użyciem znaku ampersand (&) i średnika. Większość z nich należy także do języka LaTeX. Którego zapisu używać zależy od kontekstu. Jeśli na stronie używana jest czcionka bezszeryfowa, odczytywanie liter greckich możemy zlecić zapisom LaTeX. Porównajmy: α i \(\alpha\) oraz π i \(\pi\).
