Character à not printed under Windows with certain locale / system settings
#6101 (closed) and #6216 (closed) were closed because they only reproduced under Windows 7. However, in #6101 (comment 1390693901) and https://lists.gnu.org/archive/html/lilypond-user-fr/2023-05/msg00048.html, @bersyl91 reported the same problem under Windows 10 with LilyPond 2.24.
