Note: [1][2]

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.[3]

Variations and vowel separation

The Mongolian Unicode block contains its own variation selectors (listed as format controls) for use with the traditional Mongolian alphabet:[5]

  • U+180B Mongolian free variation selector one (FVS1)
  • U+180C Mongolian free variation selector two (FVS2)
  • U+180D Mongolian free variation selector three (FVS3)

Additional variations may be also available for traditional Mongolian script characters according to the context of the character, or by using a zero-width joiner (ZWJ, U+200D) and/or a zero width non-joiner (ZWNJ, U+200C) to select the specific form. The block also contains format control named "Mongolian vowel separator" (MVS, U+180E).
