Ruby, “incompatible character encodings: UTF-8 and CP852 (Encoding::CompatibilityError)”

Question

Why

# encoding: utf-8
out=File.open(\"z\\\\test.txt\", \"a\") 
out.puts \"ç\"  
out.close
out=File.open(\"z\\\\test.txt\", \"r\")
puts out.read+\"ś\"
         


        

Answer 1

This should explain a lot

# https://pl.wikipedia.org/wiki/Kodowanie_polskich_znak%C3%B3w
inp = "zale\xBFno\x9cci".force_encoding('Windows-1250')

# inp = File.open('content-win-1250.txt', :encoding => 'Windows-1250').read

inp = inp.encode('utf-8')

File.open("tmp.txt", "wb") do |out|
    out.write(inp)
end

# file 'tmp.txt contains "zależności"
