I have this sample from a friend who has asked me what exactly the hyphen-like character at the end of the first and fourth line is. Basically, it appears to be half of a pipe, and it extends from the baseline up to the full measure of the x-height. I tried to do some of my own research, and the only thing that came close was a Mongolian character, i have now forgotten exactly which one, that actually sits above the x-height and ascends to the full cap height. This obviously isn't a match, and now, I am just curious myself as to what this break character is, and why it was used instead of the usual hyphen.
This sample, for those of you whom may be familiar, came from the following book:
