Since InDesign 21.0 BOLD styles of any font get ignored in linked WMF files

[Manuela Maria]

Since InDesign version 21.0, the following problem occurs with linked WMF files:
Text that is “bold” in the WMF file is displayed and printed as “regular” in InDesign.
This error did not occur in InDesign versions up to 20.5.1.

This behavior can be easily reproduced on both Windows 11 and Windows 10. You can use different fonts for the test, e.g., Minion Pro, Myriad Pro, Times New Roman, Arial, etc.

Test instructions:
1. Use Illustrator to create a file that contains text in regular, italic, bold, and bold italic.
2. Export this file as a WMF file.
3. Place the WMF file in InDesign 20.5.1 and InDesign 21.x.

Result:
In InDesign 20.5.1, all font styles appear correctly (see attachment: TEST InDesign 20.5.1 + Illustrator 30.1.pdf).
In InDesign 21.x, bold styles appear incorrectly as regular (see attachment: TEST InDesign 21.1 + Illustrator 30.1.pdf).

Has anyone else encountered this problem?

Gotta ask. Why are you using WMF files?

[Manuela Maria]

I create technical books that contain a large number of equations. These equations are created using MathType. The export format has to be WMF.
