The epub 3.0 reflowable and html exports are dropping characters from the export tags in the html/xhtml files. This just started happening in the last few weeks (not sure exactly when it started), perhaps early Aug 2019. My version of InDesign is upgraded to CC V14.0.3 x64, and it is still happening. I've attached 4 screenshots: 2 show the export tags in Paragraph styles, and the other 2 show the files generated by InDesign (1 in html and 1 in xhtml from an epub export). Characters are dropped from the styles. It doesn't drop a character in all styles, and it's not always the same character. I've exported MANY html/epub files, and the last few weeks is the first time it has ever done this. Please help!
Again facing this problem with the latest InD 2021 😩.
I have a similar problem with the latest InD too. It's shortens the filled names of the HTML classes in the CSS file and makes some own different names in the .html files itself. It's quite messy then :(
