Combining Glagolitic Letter I

𞀋 is a Glagolitic titlo letter: an I written above a base letter. In manuscripts, raised letters shortened words or marked sacred names. Glagolitic was created in the ninth century for Slavic Christian texts; early traces include letters on pottery at Zalavár. It gave way to Cyrillic in the east and Latin in the west, while Croatia kept it in worship and local writing, printing Glagolitic missals into the twentieth century.
