Q:

How to typeset 'tis or 'em with TeX

Sometimes 'Tis will be used to represent "this is" and 'em will be used as "them" in spoken English, but how do I typeset them with TeX? Should the tick mark be "left quote" or "right quote" or some other symbol?

A:

I think that 'tis usually means "it is", but no matter.  Typeset them as you did here, with apostrophes (single right quotes).
