readOGR does not read file names with accent

PS: surprisingly, the files with accent are well read from QGIS (however QGIS 
uses gdal as workhorse...)

 Patrick:

 Is there also a space in the file path? What is the locale, I guess
 CP1252?

 My locale is fr;Fran?ais (France)

 ... and could you try sf::st_read(), as it uses enc2utf8() internally? 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
 g?n?t/g?linotte/2017/Tr?montagne","trace_chaux_du_dombief")
 Reading layer `trace_chaux_du_dombief' from data source

 but

 st_read("./track
