Thanks. I didn't expect to have this answer to my snarky comment and I find it very interesting.

As far as I remember, I never saw it this way in Spanish literature.

You’re welcome!

I’m not very well versed in Spanish typography, so I don’t know whether they do this or not in Spain :-)

I have been fascinated by typography since a long time ago, though.

If you want another weird (foreign) typography fact, I’m French and we have very strange rules in French, in particular for book titles, how to capitalize them. As an example, a book whose title would be “Les Belles Maisons bleues” would be capitalized differently than “Des belles maisons bleues.” (Nobody knows that in France; only the people interested in typography!)
