As I understand it, the printers often ran out of certain words or letters they had often packed into a "cliche". . .this is the original meaning of the term cliche. . .and thus, being unwilling to unpack the cliches, and thus you will see some substitutions that look very odd. . .such as the exchanges of u for v, v for u, above. . .and you may wonder why they did it this way, presuming Shakespeare did not actually write the play in this manner. . . .
The answer is that they MAY have packed "liue" into a cliche at a time when they were out of "v"'s. . .possibly having used "vv" in place of some "w"'s, etc. This was a common practice of the day, as print was still quite expensive, and they didn't want to spend more on a wider selection of characters than they had to.
You will find a lot of these kinds of "errors" in this text, as I have mentioned in other times and places, many "scholars" have an extreme attachment to these errors, and many have accorded them a very high place in the "canon" of Shakespeare. My father read an assortment of these made available to him by Cambridge University
