我看到类似的线程就这样,但它仍然没有得到解决

第65行和第69行的某个地方有一些奇怪的字符,它们可能是不可见的字符,因此在一般情况下,当遇到此错误时,只需删除整行,然后再次键入即可

在这种情况下,这里有一些奇怪的字符:

cout << "(" << __FUNCTION__ << ") on line " »

cout哪个“相似线程”?最近有一次,据描述,这个问题是由于从一个网站复制粘贴代码造成的,该网站将直接引号和破折号转换为卷曲引号和en破折号。反过来,这些都是用UTF-8音译的,事实上:

302(八进制)是“零”-0xC2 273是“»”-0xBB


这将产生一个完整有效的UTF8代码“0xC2BB”,它恰好又是字符“»”。现在看看代码中的第65行——就在这里,正如错误消息所说。

您是否看了错误消息所示的第65行和第69行?特别是,您是否在这些行的末尾发现了»字符?您是否查看了第65行和第69行,如错误消息所示?特别是,您是否在这些行的末尾发现了»字符?
