	modified:   init.rb
New error case managed :
1) File encoding differs form the one specified
  For example : file encoding specified as UTF-8, but file encoded in ISO 8859-1
  => columns values / headers ending with accents run over the next column
2) Header column number is below the sample values lines columns number
3) Column delimiter not closed
