U+A678 "ꙸ" Combining Cyrillic Letter Hard Sign Unicode Character

Unicode Version 17.0

U+A678 "ꙸ" Combining Cyrillic Letter Hard Sign is a combining diacritical mark used in the extended Cyrillic script, specifically designed to be placed above or attached to a base character to indicate a hard or non-palatalized pronunciation. This character belongs to the Cyrillic Extended-B block and is typically employed in historical or scholarly orthographies for Old Church Slavonic and related early Slavic languages, where it modifies the preceding consonant by signaling that it should be pronounced without palatalization, distinct from the modern soft sign. As a combining character, it does not stand alone but must be applied to a letter such as a Cyrillic consonant, ensuring precise phonetic representation in textual contexts that require fidelity to ancient written traditions. Its usage is largely confined to linguistic research, liturgical texts, or digital typography aimed at accurately reproducing early Cyrillic manuscripts.
