Perl 6 错误消息:块 <unit> 中格式错误的 UTF-8 [英] Perl 6 error message: Malformed UTF-8 in block <unit>

问题描述

我正在尝试读取下载的 html 文件

I'm trying to read a downloaded html-file

my $file = "sn.html";
my $in_fh = open $file, :r;
my $text = $in_fh.slurp;

然后我收到以下错误消息:

and I get the following error message:

Malformed UTF-8
  in block <unit> at prog.p6 line 10

如何避免这种情况并访问文件内容?

How to avoid this and get access to the file's contents?

推荐答案

如果在打开文件时没有指定编码，它将采用 utf8.显然，您要打开的文件包含无法解释为 UTF-8 的字节.因此出现错误消息.

If you do not specify an encoding when opening a file, it will assume utf8. Apparently, the file that you wish to open, contains bytes that cannot be interpreted as UTF-8. Hence the error message.

根据您想对文件内容做什么，您可以设置 :bin 命名参数，以二进制模式打开文件.或者您可以使用特殊的 utf8-c8 编码，它将假定为 UTF-8，直到遇到无法编码的字节:在这种情况下，它将生成临时代码点.

Depending on what you want to do with the file contents, you could either set the :bin named parameter, to have the file opened in binary mode. Or you could use the special utf8-c8 encoding, which will assume UTF-8 until it encounters bytes it cannot encode: in that case it will generate temporary code points.
