U+1E018 "𞀘" Combining Glagolitic Letter Heru Unicode Character

U+1E018 "𞀘" Combining Glagolitic Letter Heru is a combining diacritical mark used within the Glagolitic script, an early Slavic alphabet created by Saints Cyril and Methodius. This character is specifically designed to be placed above or below other Glagolitic base letters to modify their sound, functioning as a typographic accent or a phonetic modifier rather than a standalone letter. It represents a specialized variant in the Unicode standard for supporting historical Slavic texts, particularly in manuscripts where such combining marks were employed to indicate palatalization or other phonetic distinctions. The character belongs to the Combining Glagolitic Marks block, which was encoded to accurately represent the complex orthographic features of the Glagolitic writing system.
