### Describe the bug

When creating a javascript file using Show Compact View, The � symbol, or the "replacement character" issue happens on some texts, it's probably related to text encoding issues, but when I create it using the template, the problem no longer occurs.
I think it's a bug in the new feature introduced in Visual Studio "Creating files using Show Compact View".
