Inter 4.1: Saving as PDF from Word gives several issues

Describe the bug In Word there are three ways to save to PDF, none of them work without problems with Inter 4.1.

1. Save as PDF. Inter.ttc works. InterVariable.ttf nothing is medium, semibold or bold:

2. Print to PDF with Microsoft Print to PDF. Inter.ttc italic gives weird characters:

3. Print to PDF with Adobe PDF. This doesn't output a PDF, but an error log:

%%[ ProductName: Distiller ]%%
Inter-Regular not found, using Courier.
%%[ Error: invalidfont; OffendingCommand: xshow ]%%

Stack:
-dict-
-file-


%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%
%[ Warning: PostScript error. No PDF file produced. ] %%

To Reproduce Steps to reproduce the behavior:

• I use the latest Word version (Version 2501 Build 16.0.18429.20132) 64 bits
• I used the latest Inter 4.1 and installed Inter.ttc and InterVariable.ttf
• I type a few words in in the font Inter and Inter Variable.
• 1. File > Save as > PDF
• 1. File > Print > Microsoft Print to PDF
• 1. File > Print > Adobe PDF

Expected behavior All fonts look as expected. A PDF file is made.
