Debian sid/unstable with *libreoffice* 4:24.2.3~rc1-3, and *gnome-shell* 44.9-1+b1. $ libreoffice --version LibreOffice 24.2.3.1 420(Build:1) Editing a DOCX document, and recording the changes, typing *begrüßt* the ß was not recognized, so *begrüt* is there. After that, I wasn’t even able to enter other umlauts like ü. Copy and pasting these characters works.
I can't confirm with Version: 24.2.3.2 (X86_64) / LibreOffice Community Build ID: 433d9c2ded56988e8a90e6b2e771ee4e6a5ab2ba CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: de-DE (de_DE); UI: en-GB Calc: CL threaded Steps: 1. Open any docx-file 2. Enable record and show track changes 3. Type "begrüßt" (Works as expected)
