Unicode Encoding error

[10cheon00]

Hello. I'm not used to writing issue, so maybe there are some ambiguity.

I was try to make sequence diagram using vscode extension. And I found your great extension and it is really useful.

But the problem occured when I save diagram into svg file. Result is this:

You can see those strange symbols, because I wrote file with Korean!

The seqdiag file is:

사용자->Pemfc: Pemfc id 전달
Pemfc->Pemfc 데이터베이스: Pemfc id값으로 삭제 요청
Pemfc 데이터베이스-->Pemfc: 삭제 완료
Pemfc-->사용자: 삭제 완료

So I tried to fixed this problem in my workspace, and I found error in this line:

switch (e.command) {
  case "export-svg":
    (t = "svg"),
      (n = this._getExportFileName(t)),
      c.writeFileSync(
        n,
        Buffer.from(e.data, "base64").toString("binary")
        /* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^ */
      );
    break;

I found this code in .vscode-server\extensions\aleksandardev.vscode-sequence-diagrams-0.4.7/dist/extensions.js, not in your repository, so I'm sorry about that I can't show actual code. It is really hard to find for me. 😥

I fixed this issue with:

-         Buffer.from(e.data, "base64").toString("binary")
+         Buffer.from(e.data, "base64").toString("utf8")

Thank you for reading this.
