Typography Test

“This is a line with quotation marks and the line’s got an apostrophe, too.”

Em-dashes work—that we know. And en-dashes work also, from 2026–. “‘Nested’ quotes?” They seem fine, though the spacing is sub-optimal.

We already know that equations work well:

π=443!125!1807!63009!39690011!=n=14((2n3)!!)2(2n3)(2n1)!.\pi = 4 - \frac{4}{3!} - \frac{12}{5!} - \frac{180}{7!} - \frac{6300}{9!} - \frac{396900}{11!} - \cdots = \sum_{n=1}^\infty \frac{-4((2n - 3)!!)^2}{(2n - 3)(2n - 1)!}.

Inline math also: (x1+x2)+(x1x2)=c(x_1 + x_2) + (x_1 x_2) = c.
