Portal:The Library of Congress, Church Slavic romanization table (2022)
“ Abbreviated words are transcribed in full, without the use of brackets. The most common symbol for abbreviation is ҃. Sometimes, omitted letters are placed above other letters in the word in Church Slavic texts (e.g., ѿ, єⷣ, ѵⷢ) , the letter added being sometimes given with a special symbol (e.g., гдⷭ҇ь) . The symbol ̾ above a letter indicates the omission of ъ or ь. ”
