Reading filename in multiple OS without encoding problem with Ruby

Question

I want to get all filenames in UTF-8. For example, after I read filename in Windows, I do

filename = Iconv.iconv(\"UTF-8\", \"Windows-1251\", filename)


        

Answer 1

I do this on Ruby 1.9 when I want to make sure things are in UTF-8:

if filename.encoding.to_s != 'UTF-8'
  filename.encode!('UTF-8')
end

Unless your OS gives a file name encoded with a coding system which doesn't support some special characters found on the file name, it can be encoded to UTF-8 without a hickup.
