I was idly doing some web searches the other day (as you do), and stumbled across this page <https://wiki.archlinux.org/index.php/Metric-compatible_fonts> at the ever-dependable Arch Wiki. My specific question was, what had happened to the “URW Palladio” font? Up until recently, this was the one that Fontconfig would offer up when I used the old “Palatino” name from Adobe PostScript days. (I used to like the way the curve of the “P” didn’t quite join up with the stem, but left a little gap with a pointy bit on the end. Ahem...) Turns out it’s still there, just under another name; it’s now called “P052” for some unfathomable reason. Anyway, that page gives a bunch of handy alternatives if you are looking for Free alternatives to proprietary fonts that preserve the metrics (widths, spacing etc), so substituting them won’t stuff up the formatting of a document.
