[R-sig-Geo] readOGR does not read file names with accent

[Roger Bivand]

Please try to install a draft version of rgdal at:

https://win-builder.r-project.org/vvWJdd1isnsR

and report on its performance for your charset:

ogrInfo("./track génét/gélinotte/2017/Trémontagne",
  "tracé_chaux_du_dombief")

ogrListLayers("./track génét/gélinotte/2017/Trémontagne")

etc. Beware that my email is probably encoded in UTF-8, so enter the 
diacriticals on your own machine.
