Range U+1800 - U+18AF
Official Chart
Wikipedia Mongolian is a Unicode block containing characters for dialects of Mongolian, Manchu, and Sibe languages. It is traditionally written in vertical lines Top-Down, right across the page, although the Unicode code charts cite the characters rotated to horizontal orientation as this is the orientation of glyphs in a font that supports layout in vertical orientation.
The block has dozens of variation sequences defined for standardized variants.
