What you have described is an XY problem. 你所描述的是一个XY问题。 It's the encoding issue and there might appear more of the characters that need to be replaced.
这是编码问题,可能会出现更多需要替换的字符。 Instead of replacing them one by one, you need to encode the whole String to
UTF-8
. 您需要将整个String编码为
UTF-8
,而不是逐个替换它们。
String s = "Constitución GarantÃa";
byte[] ptext = s.getBytes(StandardCharsets.ISO_8859_1);
String string = new String(ptext, StandardCharsets.UTF_8);
System.out.println(string); // Constitución Garantía
Consider fixing the encoding of a source where the string comes from before you actually start to work with it. 在实际开始使用字符串之前,请考虑修改字符串来源的编码。
