我正在逐行解析文件：
List<String> lines = Files.readAllLines(Paths.get(fileName), StandardCharsets.UTF_8);
问题是我需要在每行的末尾保留行终止符（因为我需要对文件中的某些行进行一些“引用可打印”解码，并且行终止符在这些行中很重要例）。
我的文件格式如下：
From: test2@test.com
To: test@test.com
Subject: Email subject
Content-Type: text/plain; charset=ANSI_X3.4-1968
Content-Transfer-Encoding: quoted-printable

我可以将整个文件作为一个字节数组读取，但这对我来说很不方便，因为我可以更方便地将电子邮件中的标题解析为文本行。
