Character strings in R can be declared to be encoded in “latin1” or “UTF-8” or as “bytes” . These declarations can be read by Encoding , which will return a character vector of values “latin1” , “UTF-8” “bytes” or “unknown” , or set, when value is recycled as needed and other values are silently treated as “unknown” .
What is encoding of a file?
An encoding standard is a numbering scheme that assigns each text character in a character set to a numeric value. Different languages commonly consist of different sets of characters, so many different encoding standards exist to represent the character sets that are used in different languages.

Why are all my file encodings returning the same data?
For your file all this encodings returns identical data (partially because there is some redundancy as you see). If you don’t know specific of your file you need to use readLineswith some changes in workflow (e.g. you can’t use fileEncoding, must use lengthinstead of dim, do more magic to find correct ones).
How to calculate the probability of a file being encoded?
The package readr, https://cran.r-project.org/web/packages/readr/readr.pdf, includes a function called guess_encodingthat calculates the probability of a file of being encoded in several encodings: guess_encoding(“your_file”, n_max = 1000) Share Improve this answer
