Perl-使用编码方法读取文件？
我不太好，当谈到编码，我想找出如何返回数据，因为它开始与相同的编码 我有一个文件，其中包含一些字符，例如，Perl-使用编码方法读取文件？,perl,file,encode,entities,Perl,File,Encode,Entities,我不太好，当谈到编码，我想找出如何返回数据，因为它开始与相同的编码 我有一个文件，其中包含一些字符，例如，“»”，当我编辑并插入到数据库中时，这些字符已经变成了» decode_entities（）不执行任何操作，而encode_entities再次对字符进行编码。因此，我创建了自己的sub来解决这个问题，但它指出，当从文件中获取数据时，它检索的格式不正确 my $file = "c:/perlscripts/" . md5_hex($md5Con) . "-code.php"; {
“»”my $file = "c:/perlscripts/" . md5_hex($md5Con) . "-code.php";
{
local( $/ ); # undefine the record seperator
open FILE, "<", $file or die "Cannot open:$!\n";
my $fileContents = unicodeConvert(<FILE>);

我怀疑，您的终端的字符集（可以是UTF-8）和perl脚本的源代码（可以在8859-1中的一些字符集感知编辑器中编辑）之间存在差异。如果您确信终端和源代码在同一个字符集中，请尝试使用utf8到脚本头（请参阅）。如果这不起作用，请尝试打印存储到数据库中的数据（增加DBI的调试日志记录）（可能是iRRerevent，因为您不将数据存储为UTF8）。一般来说，尽量提供：
locale设置名称“utf8”此外，对于HTML编码，您可能会发现重用
HTML:：Entities:：decode（）HTML:：Entities:：encode（）open FILE, "<", $file or die "Cannot open:$!\n", "UTF-8";
binmodebinmodeperl- 这不是必需的，但最好使用字典范围的文件句柄（
，而不是my$fh
）文件 - 当您在
字符串上添加换行符时，它会抑制通常为帮助您查找问题而添加的行号信息die - 如果将无法打开的文件名（或失败的SQL，或其他任何内容）放在die消息中，则调试会更容易
- 不要在Perl（5）中使用子原型。：（
）。不要把sub-uniconvert（$）
/$
/@
等放在那里。它不只是检查事物，它可能会以令人困惑的方式改变意义。只需要创建新的“内置样式”操作符%
