Asp.net core .cs file encoding is not uft-8 encoded

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

[severity:It's more difficult to complete my work]
When creating a new razor file, the cshtml file gets UTF-8 encoded but the .cs file is ANSI encoded.
This happens if you are using a swedish windows operations system with latest VS2019.

It is very easy to reproduce.

1. Install Windows 10 Swedish version
2. Install Visual Studio 2019
3. Create a new Web Project (.net Core)
4. Add a razor page
5. Check the encoding for the newly created .cs file by doing "Save as" and select "Save with different encoding" in VS.

It might sound like a small issue but it's not.
When developing code to run on AKS, the file encoding is extreamly important.

Lets say you have a file with a comment containing. UTF-8 charaters. It will compile fine on you local machine, all tests will pass, but when you check in your code and compile it on a Linux machine, it will fail.

For every file you add you need to manually change it's encoding to UTF-8. Please fix this asap.
Please don't ask me for more information. This is 100% reproducable.

Thank you for your feedback! We tried to reproduce this issue with following steps:

1. Create a C# ASP.NET Core Web App project.
2. Open Pages > _ViewImports.cshtml and edit it.
3. Go to File > Save _ViewImports.cshtml As…
4. Click “Save with Encoding…”
   The Encoding shows “Western European (Windows)” instead of “Unicode(UTF-8 with signature)”.
   

Is it the behavior of this issue? If yes, we will go through a further investigation. If not, could you help to correct us?
We are looking forward to your reply!

Yes, that’s the problem!
Both the .cs and the .cshtml should be UTF-8.

I just re-read the issue, and it's specifically talking about .cs files in the project template that we haven't done any work on. While I agree this is a gap, this isn't a regression and I'm going to punt this to 7.0. Fixing it for ASP.NET Core's projects might not be sufficient here since this affects other non-ASP.NET Core templates and scaffolding.

Docs & infra candidate? We'll need to update our pipelines / git configs to enforce UTF8 encoding for committed files.
