In the video of 19 October entitled How to Add a Border to Text Items in Dorico, we see around 1:44 an excerpt from the theme of Érik Satie’s Vexations under Engraving Options / Text / Vertical Position. The text reads THÉME rather than THÈME, i.e., with an acute instead of a grave accent. This may have been spotted since posting, but just in case.
This has been mentioned before and is probably in the queue: https://www.steinberg.net/forums/viewtopic.php?f=246&t=142226
This is already fixed. Thanks for reporting it!
