InDesign anomaly or Glyphs glitch?

When selecting text and trying to use OpenType features using a variable font in InDesign I noticed that the little OT icon shows ‘OpenType properties are not applicable’.


But when using the Opentype panel features can be selected:

However, replacing the OpenType variable with the otf’s shows that OT features can be accessed via the OT icon:

What do you mean by this exactly? What is “the otf’s”? The otf’s what? Do you mean replacing the variable OpenType font with a static OpenType font?

Yes, OpenType fonts.

Not the most obvious of nomenclature since all the fonts (static and variable) are presumably OpenType fonts.

I can’t reproduce this with any of the fonts I have lying around as both variable and static fonts – the OpenType icon works equally well for both in my InDesign.

Have you checked your variable font in FontGoggles or similar to make sure the OpenType features are correctly exported?

This can happen if the text box contains fonts from more than one font file. Even if it is just a word space.

Thanks.
