I'm not an expert and I don't really know how to handle these files: no notice, no launcher... I also tried the binary package 2.2.0 from the download page of the denemo site, but the installation failed completely (incompatibility with my 64bits Ubuntu 22.04 OS?) Finally I have downloaded from the Ubuntu Software center a 2.5.0 version of Denemo (Lilypond version 2.22) working perfectly: the é,è, etc... are well processed , trill and others ornaments appear in the denemo display and print view.I finally came back to the ante situation!
