Reading accented filenames in R using list.files

问题

I am reading county geojson files provided here into R Studio (R 3.1, Windows 8) for each of the states. I am using list.files() function in R.

For state PR, which has many counties with accented (Spanish) names viz. Bayamón.geo.json, Añasco.geo.json. The function list.files() returns shortened form of file names like An~asco.geo.json, Bayamo´n.geo.json.

And when in the next step I try to read the actual file using above filenames. I get an error that these files don't exist.

I was using system default encoding ISO-8859-1 and also tried changing it to UTF-8, but no luck.

Please help me solve this issue. How can I read files with accented filenames?
