context_page_description: Koalib is a Niger–Congo language in the Heiban family spoken in the Nuba Mountains of southern Sudan. The Koalib Nuba, Turum and Umm Heitan ethnic groups speak this language.
context_section_description: It is written using the Latin script, but includes some unusual letters. It shares a tailed R (Ɽ) with other Sudanese languages, and uses a letter resembling the at sign (@) for transcribing the letter ع in Arabic loanwords. The Unicode Standard includes R WITH TAIL at code points U+027D (lowercase) and U+2C64 (uppercase), but the Unicode Consortium declined to encode the at sign separately as an orthographic letter.
  SIL International maintains a registry of Private Use Area code points in which U+F247 represents LATIN SMALL LETTER AT, and U+F248 LATIN CAPITAL LETTER AT. However, they have marked this PUA representation as deprecated since September 2014, and the current version of their corporate PUA character assignments package recommends using U+24D0 ⓐ CIRCLED LATIN SMALL LETTER A and U+24B6 Ⓐ CIRCLED LATIN CAPITAL LETTER A for that letter instead.
