The Meiji version of the Bible has the table of contents where the Epistles are marked with a 逹 in front of every title (e.g., 逹羅馬人書—Epistle to the Romans). Do you guys know what this 逹 is? It's a Level 2 JIS X 0208 表外 that does not appear in the Chinese 康熙字典, so I guess my theory about it being some kind of a Chinese prefix ヘ is not correct. Is it some native proto新字体 of 達? If so, how do you use it in this context? How do you read it? タツ?
