How to change encoding of a file?
Another chapter of the book “Encoding is hell” 
Today I noticed that some files in one of our projects suddenly have been converted to UTF-8 where they should have been in ISO-8859-1. Ok, short question: How to convert it back?
Short Answer
Use iconv like this:
iconv --from-code=UTF-8 --to-code=ISO-8859-1 inputfile.txt > outputfile.txt
