2字节UTF-8序列的无效字节2 [英] invalid byte 2 of 2-byte UTF-8 sequence

问题描述

我正在尝试解析XML文件，但遇到错误消息2字节UTF-8序列的无效字节2。有人知道是什么导致了这个问题吗？谢谢。

最常见的是由于提供ISO-8859-x（Latin-x，如Latin-1），但解析器认为它正在获得UTF-8。某些序列拉丁语1个字符（两个连续字符，带有重音符号或变音符号）形成无效的UTF-8，特别是基于第一个字节，第二个字节有意外的高位位。

当某些进程使用Latin-1转储XML时，可能很容易发生这种情况，但是要么忘记输出XML声明（在这种情况下，XML解析器必须默认为UTF-8，按照XML规范）或索赔即使没有，也是UTF-8。

I am trying to parse an XML file with , but ran into an error message "invalid byte 2 of 2-byte UTF-8 sequence. Does anybody know what caused this problem? Thanks.

解决方案

Most commonly it's due to feeding ISO-8859-x (Latin-x, like Latin-1) but parser thinking it is getting UTF-8. Certain sequences of Latin-1 characters (two consecutive characters with accents or umlauts) form something that is invalid as UTF-8, and specifically such that based on first byte, second byte has unexpected high-order bits.

This can easily occur when some process dumps out XML using Latin-1, but either forgets to output XML declaration (in which case XML parser must default to UTF-8, as per XML specs), or claims it's UTF-8 even when it isn't.
