json_encode无法解析utf8表中的字符串[重复]

Question

This question already has an answer here:

• UTF-8 all the way through 15 answers

i've seen some posts about this topic.

I have a string that contains the letter é. I need to json_encode this string, but the function will return null. In other posts it is said that the reason behind this, is the fact that the string is not a utf-8 encoded string. So, it needs to be a utf-8 encoded string to work.

The problem is, the string comes directly from the database, and the table it originates from is encoded as utf-8. So how is the string i'm trying to parse to a json object not utf-8? Am i missing something?

Answer 1

Have you tried encoding it into UTF-8 and then saving it into the database using something like iconv(), or maybe before parsing it to a json ?

IE:

$utfchar = iconv('Windows-1252', 'UTF-8','é');

EDIT:

You Also need to set the browser's charset to utf8, this for example works:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php
    $test = iconv('Windows-1252', 'UTF-8','é');
    echo $test;
?>

<script type="text/javascript">
    var jstest = '<?php echo $test; ?>';
    console.log(jstest);
</script>
