Additional information: Philippe also tested an installer shipping brtty 5.3.1 and observed the same behavior. Then I cooked another one with as only change brltty 4.2 (same configure options) and the problem was gone (he had some wrong accented letters but tht could be due to a wrong table or something and seems anyway unrelated). I attach the font used, that presents no caveat for a sighted user. In the installer I prevent the console to be in UTF-8 mode with vt.default_utf8=0 in the command line, and the font is set this way setfont /usr/share/fonts/ter-120b.psf.gz -m /usr/share/fonts/8859-1 (as "LANG=fr_FR locale -k charmap" gives charmap="ISO-8859-1" and this font ships all needed glyphs and an UTF-8 table). I doubt that using a legacy encoding can have an influence though and anyway the rendering is OK for a sighted person. To make 100% sure that brltty be involved tomorrow I will sent to Philippe two brltty packages (5.2/5/3.1) so he can confirm that in an installed system he observes the same difference. OT and FYI I use legacy encodings in the installer because else I would need to ship in it libicuuc.so* and libicudata.so* that are heavy (around 26 MB), as dependency of brltty. By the way, am I correctly presuming that brltty needs icu enabled if the console is in UTF-8 mode? I am not 100% sure that the font used be ter-116b, it could be ter-120b if a framebuffer is available during installation so I attach both. Cheers, Didier
