Is there any filters to do it? Example: - Input: `Subject: =?utf-8?Q?Ch=E1=BB=89=20t=E1=BB=AB=2080.000=20=C4=91=E1=BB=93ng=20khi=20=C4=91=E1=BA=B7t=20taxi=20s=C3=A2n=20bay=20N=E1=BB=99i=20B=C3=A0i=20tr=C6=B0=E1=BB=9Bc=207=20ng=C3=A0y?=` - Output: `Subject: Chỉ từ 80.000 đồng khi đặt taxi sân bay Nội Bài trước 7 ngày` Thanx so mush! ---
