One further note on Word > LibreOffice > Affinity Designer workflow: it also works via Clipboard directly from Word or LibreOffice to Affinity Designer (and also between Word and LibreOffice):
As for Word, just copy the equation onto the Clipboard, then click Edit > Paste Special in Affinity Designer, and select "Enhanced Windows Metafile". You get editable equation in RGB color mode which you can easily convert to K100 by using the Layers panel which shows all composing parts of the equation in one group.
Btw: the reason Affinity Designer fails to read Word-generated PDFs containing equations is that it seems to read the equations as Windows Metafile data, rather than Enhanced Metafile. If you paste special as "Windows Metafile", you get exactly similar question marks as when placing or opening a PDF containing a Word equation. Perhaps something that could easily be fixed in future versions...
