Color font 'Nautic Alphabets Color' with 2 nautic alphabets (ttf with SVG-in-OpenType): 1. Flag semaphore (A–Z, Space, #, !, -) 2. International maritime signal flags (a–z, 0–9, _) Non-color fallback for 2. is based upon 'Mrs Beasley' font by Frank Baranowski (SIL OFL, https://fontlibrary.org/en/font/mrs-beasley).
