otftotfm issue

[Martin Münch]

Hi!

The LaTeX package SimpleIcons, https://www.ctan.org/pkg/simpleicons, 
used to use otftotfm (from the https://www.ctan.org/pkg/lcdf-typetools) 
to convert SimpleIcons.otf into SimpleIcons.pfb.

When a document used that SimpleIcons.pfb, the glyphs were shown in 
several pdf-viewers, but NOT in Adobe Acrobat Reader (on Windows), where 
there was just white space. (Well, the icon was there, but at about 
0.00001 % of intended size.)

When converting SimpleIcons.otf into SimpleIcons.pfb by Fontforge, then 
also Adobe Acrobat Reader (on Windows) correctly presents the glyphs/icons.

Thus something with the font conversion via otftotfm is amiss.

The SimpleIcons package now uses Fontforge, but otftotfm should be repaired.

The issue has already been discussed at

https://tex.stackexchange.com/questions/689446/compatibility-issue-between-the-simpleicons-package-otftotfm-and-adobe-acrobat

and

https://github.com/ineshbose/simple-icons-latex/issues/11

which give additional insights but no fix for otftotfm.

Who should do what to otftotfm to fix the issue?

Yours

Martin
