Glagolitic Small Letter Djervi at U+2C3C is a lowercase letter of the historic Glagolitic script, used to represent the small form of djervi in encoded Old Church Slavonic and related Slavic texts. It belongs to the Glagolitic block, which contains the letters needed for modern digital transcription of Glagolitic manuscripts and printed sources. Its main real-world use is scholarly: editors, linguists, paleographers, and digital humanists use it when reproducing Glagolitic-script material without converting it to Cyrillic or Latin transliteration. In editions of Old Church Slavonic, Croatian Glagolitic, or Church Slavonic sources, the letter may appear as part of words copied from the original script, preserving distinctions that matter for spelling, phonology, and manuscript comparison. Outside academic and archival work, it is uncommon. It may be encountered in font testing, Unicode charts, educational material about Slavic writing systems, or cultural projects connected with Glagolitic heritage. Because Glagolitic letters are not widely supported in everyday fonts, this character is more likely than ordinary modern letters to appear as a missing-glyph box on older systems.
