问题描述
我在使用PHP将ISO-8859-1数据库内容转换为UTF-8时遇到一些问题。我运行以下代码测试：
I'm having some issues with using PHP to convert ISO-8859-1 database content to UTF-8. I am running the following code to test:
// Connect to a latin1 charset database
// and retrieve "Georgia O’Keeffe", which contains a "’" character
$connection = mysql_connect('*****', '*****', '*****');
mysql_select_db('*****', $connection);
mysql_set_charset('latin1', $connection);
$result = mysql_query('SELECT notes FROM categories WHERE id = 16', $connection);
$latin1Str = mysql_result($result, 0);
$latin1Str = substr($latin1Str, strpos($latin1Str, 'Georgia'), 16);
// Try to convert it to UTF-8
$utf8Str = iconv('ISO-8859-1', 'UTF-8', $latin1Str);
// Output both
var_dump($latin1Str);
var_dump($utf8Str);
当我在Firefox的源代码视图中运行时，确保Firefox的编码设置设置为Western -8859-1），我得到：
When I run this in Firefox's source view, making sure Firefox's encoding setting is set to "Western (ISO-8859-1)", I get this:
到目前为止，还不错。
So far, so good. The first output contains that weird quote and I can see it correctly because it's in ISO-8859-1 and so is Firefox.
在我将Firefox的编码设置更改为UTF后，第一个输出包含这个奇怪的报价，我可以正确地看到它，因为它在ISO-8859-1中。 -8，它看起来像这样：
After I change Firefox's encoding setting to "UTF-8", it looks like this:
报价去了哪里？ iconv（）是否应该将其转换为UTF-8？
Where did the quote go? Wasn't iconv() supposed to convert it to UTF-8?
推荐答案
U + 2019 RIGHT SINGLE QUOTATION MARK不是ISO-8859-1中的字符。它是中的字符，为0x92。实际的ISO-8859-1字符0x92是很少使用的，称为私有使用2。
U+2019 RIGHT SINGLE QUOTATION MARK is not a character in ISO-8859-1. It is a character in windows-1252, as 0x92. The actual ISO-8859-1 character 0x92 is a rarely-used C1 control character called "Private Use 2".
看来这是发生在这里。将ISO-8859-1更改为windows-1252。
It appears that this is what's happening here. Change "ISO-8859-1" to "windows-1252".
