About
Noto Sans Nabataean exists primarily to ensure the Nabataean script — the ancient precursor to the Arabic alphabet — can be rendered digitally without missing glyphs. Its single weight is sufficient for its narrow scholarly use cases, including academic publications, digital archives, and historical texts. It is an essential utility font rather than a design tool.
Classification
Covers the ancient Nabataean script, an Aramaic-derived alphabet used by the Nabataean kingdom around the first century BCE to first century CE. A single Regular weight reflects its specialist, scholarly application.
