However, we have a downstream difficulty, which is that current GDAL
poLayer->GetName() appears to return UTF-8 in both sf::st_layers() and
rgdal::ogrListLayers(), instead of native (CP1252 or other). However, this
is seen as native or unknown in R, so messes up choosing the first or
single layer if only a dsn is given in a non-UTF-8 charset locale. I'm
going to assign
Encoding(layers) <- "UTF-8"
layers <- enc2native(layers)
as a work-around.

On a CP1252 Windows 7 system, R 3.4.3 patched, current CRAN rgdal and sf, the
dsn is not affected by diacriticals, but the layer name is. Putting
enc2utf8() around the layer name resolves the problem for me, so for Patrick:
st_read("./track génét/gélinotte/2017/Trémontagne",
enc2utf8("tracé_chaux_du_dombief"))
or
readOGR("./track génét/gélinotte/2017/Trémontagne",
enc2utf8("tracé_chaux_du_dombief"))
should work.

Is there also a space in the file path? What is the locale, I guess

My locale is fr;Français (France)

If that works, the same may be used in rgdal.
st_read has the same issue: reads the file with no accent but not with
accent:
library(sf)
st_read("./track
génét/gélinotte/2017/Trémontagne","trace_chaux_du_dombief")
Reading layer `trace_chaux_du_dombief' from data source

but
st_read("./track

Does
st_read("./track génét/gélinotte/2017/Trémontagne",
enc2utf8("tracé_chaux_du_dombief"))
work?
