What software do you test your fonts with? I test in Illustrator, Indesign, Photoshop, Textedit, Wordpad, and Word. And for testing in the non-Adobe apps I just open a file and make sure all of the characters appear without .notdef showing up. I’ve never tested a font in QuarkXpress, CorelDRAW, or any of the FOSS apps. Is there some important software other than the basic Adobe/Apple/Microsoft apps that I should worry about?
Weights below 250 don't work correctly, and you can see immediately if there are uncovered unicode ranges set (unless you have a .notedef glyph with no countours):
Recently I bought a license to H&Co Requiem only to find that Word 2010 chops off the descenders.
Given that Word still has not fixed its artificial small caps problem, I gave up on Word entirely and use LibreOffice Writer or Scribus instead, neither of which mangles fonts like Word does. Meanwhile Google won’t let Outlook versions older than 2016 to even connect to Gmail. To this day the Word team still cowers and grovels obediently before the angry Gods Of Document Reflow.
If you are forced to care about customers who are forced to care about Word, pay close attention to the vertical metrics and chopped off extenders. I don’t know specifically how to fix it, but you should at least check to see if the problem affects your fonts. I don’t know whether the advice in the recent vertical metrics thread covers behavior in Word or not.
For the record: I have synced Requiem via Monotype App and I see no chopped descenders, but I have Word 365.
After testing my fonts in Word and on my printer and before finishing them and publishing, I download the font on our two Kindle readers to test on the novel(s) we're reading. I correct some glyphs following this, be it contours, metrics or kerning.
I don't know if the Kindle way to treat Truetype fonts is the nec plus ultra but I'm satisfied as it recognizes most of the special features.
This could be the subject of another topic.
Another thing: a check if at least uprights and italics are linked would be appreciated:
