我对文本编码和字符集感到困惑.出于很多原因,我必须在即将开展的工作中学习非Unicode,非UTF8的东西.

我在电子邮件标题中找到"charset"一词,如"ISO-2022-JP",但在文本编辑器中没有这样的编码.(我环顾了不同的文字编辑.)

文本编码和字符集之间有什么区别？如果您能向我展示一些用例示例,我将不胜感激.

正如标题所示，Jackson 无法读取 utf-8。

第 37 行：

ArrayNode arrayNode1 = objectMapper.readValue(bansFile, ArrayNode.class);\n

21:48:55 [严重] com.fasterxml.jackson.core.JsonParseException：无效的 UTF-8 起始字节 0xb3\nat [来源：（文件）；行：18，列：38]

这里是第18行，无法读取UTF-8“\xc5\x82”

"reason" : "管理员 nie poda\xc5\x82 powodu banicji"

整个堆栈跟踪
