Cannot change visual studio code settings -

i try change visual studio code settings cannot edit anything. should ? want set encoding

"files.encoding": "iso 8859-1", 

you need make settings.json file , enter settings overrides there. on windows c:\users\username\appdata\roaming\code\user\settings.json, add settings, example:

{   "files.encoding": "iso 8859-1",   "editor.fontsize": 18,   // ....other settings } 

you have option add settings on project basis - add settings file .vscode\settings.json inside project root folder.
