U+180F "᠏" Mongolian Free Variation Selector Four Unicode Character
Unicode Version 17.0
᠏
U+180F "᠏" Mongolian Free Variation Selector Four is a specialized invisible formatting character used in the Mongolian script, specifically within the Unicode Standard to indicate a stylistic or contextual variant of a preceding Mongolian letter without altering its core meaning. Unlike selectors one through three, which are actively used in modern Mongolian text rendering to control glyph shapes like final or isolated forms, U+180F was originally defined for potential future use but has been deprecated in later versions of the standard and is not recommended for new text, as its intended function remains largely unspecified and unsupported by common fonts and rendering engines.
