Far too frequently for my tastes, MS Word's automatic replacement of straight apostrophes with curly ones seizes up and replaces the wrong letter. Right now, I have a document where I can reproduce this as will. Hence this recording.

Of course, as soon as I close and reopen the document, the problem will be gone.

This has been going on for YEARS.

Sigh.

@betalogue Have you considered #LibreOffice? It handles MS Office files quite nicely.
@countdracula Same old question, same old answer: When most of your clients use Microsoft Office, you really have no choice but to use Office yourself. I’ve kept a (distant) eye on LibreOffice, but I cannot trust that it will provide the level of document compatibility that I need, and its UI is just too alien for me, not to mention incompatible with other macOS tools that I use. When I can, I use #NisusWriterPro. Otherwise, I have to use MS Word.
