"%uXXXX" is a non-standard scheme for URL-encoding Unicode characters. Apparently it was proposed but never really used. As such, there's hardly any standard function that can decode it into an actual UTF-8 sequence.
"%uXXXX" 是用于 URL 编码 Unicode 字符的非标准方案。显然它被提议但从未真正使用过。因此，几乎没有任何标准函数可以将其解码为实际的 UTF-8 序列。
It's not too difficult to do it yourself though:
不过，自己做并不难：
$string = '%u05E1%u05E2';
$string = preg_replace('/%u([0-9A-F]+)/', '&#x;', $string);
echo html_entity_decode($string, ENT_COMPAT, 'UTF-8');
This converts the %uXXXXnotation to HTML entity notation &#xXXXX;, which can be decoded to actual UTF-8 by html_entity_decode. The above outputs the characters "??" in UTF-8 encoding.
这会将%uXXXX表示法转换为 HTML 实体表示法&#xXXXX;，它可以通过html_entity_decode. 以上输出字符“??” UTF-8 编码。
