Create PDF from Web Page uses only light weight fonts
System setup: Acrobat DC (CC) 21.0 on Mac OS X Big Sur 11.2.3.
I wanted to make a PDF from this URL https://developer.apple.com/fonts/TrueType-Reference-Manual/ using File > Create > PDF from Web Page...
The resulting PDF used Helvetica Neue Ultra Light for the body text which is almost completely unreadable. Some type was set in Courier (as it was monospaced on the webpage). The webpage header footer references were in Times.
Then I tried this again, after changing the font preferences here: Create PDF from Web Page > [Settings...] > Web Page Conversion Settings / [Settings] > Language Specific Font Settings changing Language Script Western European (& Unicode) to Helvetica Now Text.
The resulting PDF is still the same using Helvetica Neue Ultra Light.
Well, I can use Edit PDF to change the font choice to Helvetica Now. Only it messes up the spacing (unsurprisingly). Also I can only select all text on one page at a time, and the document is over 800 pages.
Checking the website I see that Apple is only using SF Pro Display, SF Pro Text, and Courier. I download SF Pro fonts from Apple's Developer Site, and install them on my system. Restart Acrobat DC and try to make a PDF again.
The PDF now uses SF Pro Display and SF Pro Text, but only the light versions of them.
I open Font Book and disable the light versions. Restart Acrobat DC and try to make a PDF again.
The PDF continues to use light versions of SF Pro Display and SF Pro Text.
I then manually remove the light variations of SF Pro, also the light variations of my Helvetica Now just in case. Restart, etc.
Now the type is rendered using the regular weights of SF Pro. Courier is on the delicate side but it's not used that much and so tolerable. Also I have no idea if I can remove all lighter versions from the system without breaking something important.
I can see the substitution of Helvetica Neue, but it seems that Acrobat should also try to match the weight. Appropriate weights were available, but it went for the lightest weight as regular. It doesn't seem right that I should have to uninstall anything to prevent this from happening.
This is the first time I tried this in Acrobat DC, but it seems like a bug to me. Any comments on what I might have missed here?
