# Page 153 - Writing a function that returns a value

At the end of this section there is a note box that explains that we could use the `C` format code to format the output as currency. If you are running on a computer in a culture that uses Euros then to show the Euro currency symbol you must enable UTF-8 encoding. 

Add the following statement near the top of the code file before doing any writing to the console:

```cs
Console.OutputEncoding = System.Text.Encoding.UTF8;
```

In Step 2, I show text that must be entered as a single line at the command-line, as shown in the following command formatted as in the print book:
```
dotnet ef dbcontext scaffold "Filename=Northwind.db" Microsoft.
EntityFrameworkCore.Sqlite --table Categories --table Products --output-
dir AutoGenModels --namespace WorkingWithEFCore.AutoGen --data-
annotations --context Northwind
```

Here is the same command as a single line to make it easier to copy and paste:
```
dotnet ef dbcontext scaffold "Filename=Northwind.db" Microsoft.EntityFrameworkCore.Sqlite --table Categories --table Products --output-dir AutoGenModels --namespace WorkingWithEFCore.AutoGen --data-annotations --context Northwind
```

I recommend that you copy and paste long commands like this from the eBook into a plain text editor like Notepad, and then make sure that the whole command is properly formatted as a single line, before you then copy and paste it to the command-line. 

Copying and pasting directly from the ebook is likely to include newline characters and missing spaces and so on that break the command.
