I've read previous question/answers on this topic (e.g. this), but am still in the dark. The problem I'm trying to solve: Which font combination for XeLaTeX will at the same time provide a legible and attractive visual aspect of the final document and the ability to copy/paste out of and search inside the PDF file. The issue is the separation of ligatures.
Here's a small example of my .TEX file:
\documentclass[12pt,letter]{article}
\usepackage[margin=1in]{geometry}
\usepackage[sf,bf]{titlesec}
\usepackage{parskip}
% Font settings
\usepackage{fontspec}
\defaultfontfeatures{Ligatures=TeX}
\setmainfont{Minion Pro}
\setsansfont{Myriad Pro}
%% The document

Should the cut-off for ``flat" be selected in a more scientifically founded way?
The three sub-regions are not very homogeneous: there is "noise", that is, isolated pixels or small structures within one region (say, ``north") that are classified as a different region (say, ``south"). Should these be smoothed (via a median filter, for example, or a morphological filter)?

I have tried this with the combinations
- Minion Pro/Myriad Pro
- Linux Libertine O/Linux Biolinum O
- Cambria/Calibri
Any of the three would be acceptable for my purposes, though I like the Minion/Myriad combination most. But each of them fails to separate different sets of ligatures. Cambria is overall worst. Libertine/Biolinum is good for he fl/fi/ffl/ffi ligatures, but the (beautiful) capital Q in Libertine, and capitalized Th are an issue. Below is a screenshot of the result of copy/pasting from the PDF output.
Are there any settings in fontspec
or \defaultfontfeatures
that I could change?
