Folks, we're not successfully finding a repro for this issue. I've only seen the ANSI color code characters show up when i redirect console output to a text file and then open that file in notepad. We've tried this on multiple win10 machines. Can you help us find a good repro?

Repro Steps

1. Create a VM in Azure running Windows Server 2012 R2 Datacenter
2. Install "Windows x64 .NET Core SDK Installer" version 1.0.0-rc2-002470
3. Open command prompt (cmd.exe)
4. Run dotnet foo

Output

C:\Windows\system32>dotnet foo
←[1m←[31mNo executable found matching command "dotnet-foo"←[39m←[22m

I don't see it happening anymore with 1.0.0-rc2-002476

[mikeharder]

Still repros on Windows Server 2012 R2 with 1.0.0-rc2-002476.

Just saw this on Ubuntu 14.04 running inside docker:

(sorry about the huge size, apparently it's the OneNote screen clipping not handling HiDPI correctly)

It's not really unicode, it's just an plain old ascii 0x1b, as proved like this:

For whatever reason I did not see this with 1.0.0-rc2-002476 but it is actually still happening on Win10 and 1.0.0-rc2-002655:

PS C:\temp\publishout> dotnet pu
�[1m�[31mNo executable found matching command "dotnet-pu"�[39m�[22m

[ghost]

I can't reproduce it with 1.0.0-preview2-003121 on Windows 10 and OSX 10.11.

Running on Linux container works fine now. Maybe can close.

OK, since it seems the issue has resolved with newer versions, closing. Please reopen if it repros again with latest.
