Q:

vscode: set encoding for files with a specific extension

I'm working with visual studio code to edit classic asp pages. 
In order not to break everything, I need .asp files to be read and written using Windows 1252 encoding.
Is there some way to configure it? if it could be done on a folder/project/workspace basis that would be great.

A:

See language-specific settings.  so something like
 "[asp]": {
    "files.encoding": "windows1252"
  },

assuming asp is your language name, if not, put your language there.
If you want it for only a specific workspace put that into that workspace settings.  
Command palette/"Open Workspace Settings"
