有一個(gè)辦法。將所有 uXXXX 替換為其 HTML 表示形式，並執(zhí)行 html_entity_decode()
即echo html_entity_decode("Jalostotitlán");
u1234 形式的每個(gè) UTF 字元都可以在 HTML 中列印為 ?。但是進(jìn)行替換非常困難，因?yàn)槿绻麤](méi)有其他字元來(lái)標(biāo)識(shí) UTF 序列的開(kāi)頭，則可能會(huì)出現(xiàn)很多誤報(bào)。一個(gè)簡(jiǎn)單的正規(guī)表示式可能是
preg_replace('/u([\da-fA-F]{4})/', '\1;', $str)
