I typeset a scanned and ocred copy of an old book. It used a moderately common font except with extremely narrow line spacing. None of the tools I had supported a line spacing narrower than the spacing chosen by the font designer, so I had to create a hacked version of the font to make it work.
Traditionally, the leading was separate from the type. Nowadays it isn't, and that can be a huge pain in the bum.
