You can use Regex to transform your reference text to one non-space character per line. Vertically select them and copy to clipboard. Then in the box file, vertically select the characters and replace them with the clipboard content.
That's the trick I normally use in editing box files. Good programming editors like jEdit or Notepad++ usually support vertical selection of text.
