我想匹配selenium中的文本编码，但我得到像图片的错误

i'm trying make auto test by selenium but I'm getting unwanted results i must get text in the target website. i want the "4 인용 여성 기숙사 형 객실 내 침대 (2 층 4 인 도미)" but,

and my code is.

 $aa = $driver->findElement(WebDriverBy::xpath('//* 
 [@id="root"]/div/div[2]/div/div/div[1]/div[2]/div/div/div/h1'))->getAttribute('innerText');
 Log::alert($aa);

i got this

check with the mb_detect_encoding () function, the result is utf-8 so, iconv ('UTF-8', 'UTF-8, $ aa'), the same thing happens.

how i get the data i want?

please tell me about what's wrong
