Why will LibreOffice no longer show or accept y's and z's?

[Griffolino]

So this .docx file suddenly shows up on screen with all its y’s and z’s missing, and when I attempt to type in a y or a z, nothing happens.

Ah, I’ve found the fault: it’s in the font. Thanks all.

What version of the LibreOffice and Operating System are you using?

… and please provide a sample document showing the artifact.

And what locale setting are you using? (The position z/y keys on my Hungarian keyboard is different (reverse) than on an English keyboard.)

English: QWERTY… / Hungarian: QWERTZ…

I have tried with both 6.3.6.2 and 7.0.1.2.JCB Publications 9.20.docx

Lots of y’s and z’s in that document, displayed by LibreOffice 6.4.6

I can insert z and y characters into your sample file with my permanently installed and the portable LibreOffice versions. And I can see all of previously inserted z and y characters of the document.

But there are missing (substituted) fonts in your documets. I have not

Looks like a duplicate/damaged font issue. See I can’t see the letters x, y, z on any website…
