U+1861 "ᡡ" Mongolian Letter Sibe U Unicode Character

U+1861 "ᡡ" Mongolian Letter Sibe U is a glyph in the Mongolian script block, specifically used to represent the vowel sound "u" or "ū" in the Sibe language, a Tungusic language spoken by the Sibe people in Xinjiang, China. This character is distinct from the standard Mongolian letter U due to its slightly different form and phonetic function in the Sibe orthography, which is an adaptation of the traditional Mongolian script. It is encoded in Unicode to support the digital representation of Sibe writing, enabling its use in modern computing and text processing for this minority language.
