Converting file from 2023 to 2022

[michaelr26894937]

I had a user accidentally create a long book interior in InDesign 2023. We had to convert this file to 2022 after it was proofread, and during conversion several words broke differently causing slight reflow.

When I highlight one of the offending lines that reboke or moved a word, I noticed the only difference is the value of the kerning.

For example, in 2023 the line of text kerning is 0:

but after conversion to Indd 2022 the value now read (metrics):

Is this a preferences issue? A bug? Any help would be appreciated.

When forced to convert between versions, a desperate last resort, yes this sort of thing can happen. It is not a bug, it's just how things are. Careful checking is needed and you may need corrections.

You would be far better off using 2023. IDML conversions are never perfect, especially with a very long document.

I guess I was wondering if the kerning engine within InDesign underwent major revisions. I remember this happened once before (between Indd CS3 and CS4, I believe?)

It just seems odd that literally every value is the same except for the kerning. Glad it is not user error (other than accidentally opening in the wrong InDesign) . . .
