The two questions are asking very similar things—how does one change the font for a particular piece of text—but there's a fairly crucial difference: the font.
Because of that difference, I'd hesitate to mark the latter as a duplicate of the former since it really doesn't answer the question of how to get Chancery in particular. However, I don't think we really need two questions asking for the same basic information.
(Even though the two questions ask about different fonts, I feel a little bit silly for having answered a nearly duplicate question rather than voting to close. Actually, with a tiny bit of searching, I found another question that contains the answer of how to change the font.)
What should be done here? Should I delete my answer, leave a comment with the particular font family name, and vote to close as a duplicate pointing to one of the other questions?
