Java Split ISO-8859-1 String with "broken vertical bar"

Question

I read from a third system an ISO-8859-1 coded String. I have to split this String with the character ¦. This char has in ISO-8859-1 the value 166. The following code doesn't work, because the value in Java (UTF-8) of ¦ is 65533.

String [] parts = isoString.split("¦");

I am stuck... How can I solve this? Thanks

Answer 1

Working code:

String s = new String(new byte[] {'a', 'b', (byte) 166, 'c', 'd'}, 
                      StandardCharsets.ISO_8859_1);
String[] split = s.split("\u00a6");
System.out.println("split = " + Arrays.toString(split));
// prints split = [ab, cd]

您首先需要将ISO-8859-1 字符串正确解码为 Unicode 表示，以便您可以使用您提供的 Unicode 字符串文字 ( | ) 将其拆分——当然，假设您正在使用 Unicode 编码编译程序。
