Convert UTF-16LE to UTF-8 in php
提问by ??????
I use iconvphp function but some characters doesn't convert correctly:
我使用iconvphp 函数，但有些字符不能正确转换：
...
$s = iconv('UTF-16', 'UTF-8', $s);
...
$s = iconv('UTF-16//IGNORE', 'UTF-8', $s);
...
$s = iconv('UTF-16LE', 'UTF-8', $s);
...
$s = iconv('UTF-16LE//IGNORE', 'UTF-8', $s);
...
I also try mb_convert_encodingfunction but can't solve my problem.
我也尝试mb_convert_encoding函数但无法解决我的问题。

iconvsupports the UTF-16LEencoding.
iconv支持UTF-16LE编码。
You can use it to transpose the encoding from UTF-16LEto UTF-8:
您可以使用它来将编码从UTF-16LEto转置UTF-8：
$result = iconv($in_charset = 'UTF-16LE' , $out_charset = 'UTF-8' , $str);
if (false === $result)
{
throw new Exception('Input string could not be converted.');
}
See iconvDocs.
请参阅iconv文档。
I'm just wondering if all code-points available in UTF-16LEare available in UTF-8. But I assume that this should fit in your case.
我只是想知道，如果在所有可用的代码点UTF-16LE是可用的UTF-8。但我认为这应该适合你的情况。
Edit:I was not able to reproduce the problem on a box of my own, but on another boxI ran into this notice:
编辑：我无法在我自己的一个盒子上重现这个问题，但在另一个盒子上我遇到了这个通知：
Notice: iconv() [function.iconv]: Wrong charset, conversion from
UTF-16LE' toUTF-8' is not allowed in ...
注意： iconv() [function.iconv]: 字符集错误，
UTF-16LE' to在 ... 中不允许从UTF-8'转换
Looks like that not all iconvversions can actually convert UTF-16LEto UTF-8.
看起来并非所有iconv版本都可以实际转换UTF-16LE为UTF-8.
It might be a workaround to use mb_convert_encodingDocsinstead, at least it was in this case (Demo):
使用mb_convert_encodingDocs可能是一种解决方法，至少在这种情况下是这样（演示）：
$result = mb_convert_encoding($str , 'UTF-8' , 'UTF-16LE');
