Can you check this pull request (new errors managed)

Hi,

Can you check this pull request, that manages more error cases :
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

Thanks a lot
