All typography sites seem to be in agreement about most typefaces:
- The lower-case letters b, d, f, h, k, l, and t usually have ascenders.
- The lower-case letters i and j usually have a dot on top, called tittle if one really needs a name for them.
But are tittles ascenders? A few sites boldly assert this. For example, search on Google for
what letters have ascenders and you will get this page, which proudly proclaims that i and j are (sic) ascenders. But that page is pretty dubious since it also claims that all capital letters have ascenders and it's not very precise about a letter having an ascender vs. a letter being and ascender.
More reputable-looking (IMHO) sites seem to just skirt the question. They’ll proudly declare that b and h are two letters that have ascenders and stay quiet about the other letters.
Is this a thing where there is general agreement among professionals and a lot of us amateur typographers are wrong? Or is this a cultural thing where there are competing schools of thought that have had schisms about this issue but typographers are so polite everyone has just agreed to not mention it? Am I about to restart a culture war by asking this question?
And how about diacritics?
