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

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