I recently asked here, a question about the choice of OpenType Unicode fonts for my PhD thesis. After considering the comments and answers to the question, I decided to use Libertinus for both text and math.

However, one of the comments to my question keeps nagging my inner self. To paraphrase it, they cautioned me that I shall end up having to do some more manual kerning in math mode.

I do not possess an in-depth knowledge about typographic convention and best practices. Inspired by this question wherein that user had asked about when should they be using non-breaking space, in the same vein, I would like to seek best practice guidance on the following issue:

When (and why) do we need manual kerning for math content when using certain fonts?

  • Why? Aesthetics, maybe? – Oleg Lobachev Apr 21 '18 at 18:49
  • @OlegLobachev or in addition, it may well be an established typograpic practice, similar to standard conventions for hyphenation, leading and tracking. I am interested in such best practices and how to achieve them in a latex document. – Krishna Apr 21 '18 at 19:13
