Question

我们在名下提交了以下数据：

{
  "en":"Nokia-130",
  "ar":"\u0646\u0648\u0643\u064a\u0627 130 (2017)",
  "ch":"\u8bfa\u57fa\u4e9a130\uff082017\uff09"
}

我们正试图点击：

SELECT json_extract(NAME, "$.ar")
FROM products
WHERE json_extract(NAME, "$.ar") LIKE '%\u0646%';

它工作正常并给出了结果，但是当我们点击

时

SELECT json_extract(NAME, "$.ar")
FROM products
WHERE json_extract(NAME, "$.ar") LIKE '%\u0646\u0648%';

它没有用。
