I suggest you
uninstall MS Office, reinstall from
MS media, and reactivate the license. If you've activated the license more than 2-3 times before, you may have to call MS to get a one-time reactivation key (or whatever it's called). Then apply
all the MS Office updates via Windows Update (WU), you'll probably have to run WU more than once.
And then, before doing anything to Word
- Download Kovid Goyal's test DOCX ==>> demo .docx file. Open it in the just installed Word 2013, make a trivial change and save it. Push that through the tools you use to create the EPUB and post the DOCX and EPUB here.
- Download this small ODT from Oasis Open ==>> https://www.oasis-open.org/committee...Types-wd-1.odt. Load that into the just installed Word 2013, make a trivial change and save it as DOCX. Push that through the tools you use to create the EPUB and post the ODT, DOCX and EPUB here.
Then install your typographical correction macro, apply it to Kovid's DOCX and Oasis Open's ODT, save the resultant DOCXs, convert them to EPUB and post the ODT, DOCXs and EPUBs here.
============================
Re the 'letter-spacing'
In Word 2013 right click in a para that the gets the 'letter-spacing' property, select Font->Advanced, the following are the standard default settings that will not create 'letter-spacing' properties.
The top group of controls is what you would set if you
wanted non-standard spacing - note the Set Default button at the bottom. If they are not as shown above, then make them so and click Set Default.
I'll ask again, can you translate
Policepardfaut into English please, the only suggestion I get from online translators is "Police Parfait".
