Dear all, I write now with a separate tex4ht bug, a very small one, no fatal error, just a space missing between a book's series title and the number that goes with it in tex4ht/biblatex output, which is a bit tedious to fix manually in the ODT output each time. I have described the problem here (this time with MWE from the start!): https://tex.stackexchange.com/q/628083/44742 <https://tex.stackexchange.com/q/628083/44742>
Best, Alex
