I would like to know how can I change the encoding of my CSV file when I import it and parse it. I have this code:

```
csv = CSV.parse(output, :headers => true, :col_sep => ";")
csv.each do |row|
  row = row.to_hash.with_indifferent_access
  insert_data_method(row)
end

```

When I read my file, I get this error:

```
Encoding::CompatibilityError in FileImportingController#load_file
incompatible character encodings: ASCII-8BIT and UTF-8

```

I read about `row.force_encoding('utf-8')` but it does not work:

```
NoMethodError in FileImportingController#load_file
undefined method `force_encoding' for #<ActiveSupport::HashWithIndifferentAccess:0x2905ad0>

```

Thanks.
