In the Readme, it is stated: "The alphabet is not static ; some glyphs that we use today did not exist in the 17th century. For example, capital “V”, capital “I”, and the “@” sign."
Also one may examine the spellings within the preface to the 1611 itself in Roman typeface, where "unto" is spelt "vnto," "JESUS" is spelt "IESVS," "give" is spelt "giue," and so on. The text given in blackletter typeface follows these spellings as well.

In the 1611 KJV text, every leading or capital "u" is a "v", while every capital "j" is in reality a capital "i". This may be verified by comparing the 1611, available here: https://archive.org/details/1611theauthorizedkingjamesbible_202001, against the Oxford Roman typeface reprint, available here: https://archive.org/details/av1611oxford1833part2/AV1611oxford1833part1/page/n181/mode/2up
