The problem i find is that InDesign CS2018 (and basically all versions of InDesign CC) does not dependably handle Yiddish text. Sometimes it will break words at arbitrary points when it comes to the end of the line. See attached screenshot. I've highlighted certain words in green. You can see that when some of them reach the end of the line, they are getting broken in the middle of the word. Hyphenation is turned off, this should not be happening.

I've attached an InDesign package with this page and its font, if you'd like to play with it and see what's going on.

There is no input keyboard that works well with InDesign CC. (This is one that works fine with InDesign CS6. Unfortunately our office is using InDesign CC2018 for all our other projects, it's a bit complicated switching back and forth between versions of InDesign just so our editor can make changes in InCopy.
