Corrupted word kerning

[gh68226773]

Indesign 2017 (12.0.0.81)

Mac OSX 10.11.5

Original document designed and packaged using Indesign 2014 (version unknown)

Package Zipped and emailed to me.

Decompressed, opened in Indesign 2017, changed any items from Black to PMS Color, export PDF.

Somewhere in there, all the word kerning was changed from the original Optical to a corrupted Metrics, which makes "every other" line of text appear to be missing a space between each word - see attached screen pic.

I have the original Zip file, and can not reproduce the first results.

If I copy/paste the text box, the spaces return, but the kerning is still at Metrics, which causes reflow.

Any ideas, or is it a case of Corrupt Computer Gods?

Thanks.

Open it, save as IDML, reopen and see what happens...

I did try that, spaces returned, but kerning was still set for Metrics - causes reflow.

Fixing was the easy part, finding a reason why it happened is what I'm after.

The issue of the missing Optical Kerning when exported as IDML has been noticed before; see, f.e., Missing elements in INDD to IDML conversion

Only thing you can do is report this to Adobe as a bug: Feature Request/Bug Report Form – and hope your vote finally is enough to tip the scales into them fixing it.

That's not exactly what happened.

I opened "their" Indesign 2014 document, not the IDML, in Indesign 2017.

And I can not reproduce the error.
