delphi清理txt文件多余的空格

PDF文件转存为文本，多了一堆不需要的空格，写个小程序处理一下，没逻辑，直接上代码。

delphi用的是XE11.3

unit UnitSmallMain;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs,
  FMX.Controls.Presentation, FMX.StdCtrls, FMX.Memo.Types, FMX.ScrollBox,
  FMX.Memo;

type
  TForm4 = class(TForm)
    btn1: TSpeedButton;
    Memo1: TMemo;
    procedure btn1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form4: TForm4;

implementation
