Voice instrument name not capitalizing accented letters

I try to reproduce an old song I composed into Dorico for tenor and piano. I changed the default “Tenor” label for the French “Ténor”. I now see a capitalized label, except for the accented E. Now it looks like “TéNOR”. Please see screenshot.

Also, is it possible to turn off the automatic capitalization of voice labels?

It is possible to turn this off, on the Staff Labels page of Engraving Options. Thanks for alerting us to this bug, which we will take care of.
