How to add a new encoding to vscode

Question

does anyone know of a way to add a new encoding to VS Code? Either by way of adding a new encoding file or setting up an extension to do on the fly conversion? Specifically I'm trying to add support for decoding IBM EBCDIC (1047) to VS Code. Any help would be appreciated!

I haven't been able to find any clues as to how one might go about doing this.
