如何在PHP CURL POST请求中发送法语字符？

curl_setopt($ch, CURLOPT_ENCODING, 'UTF-8');

$data = array(
    'message' => utf8_encode('Bonjour le monde')
);

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

// 创建CURL资源
$ch = curl_init();

// 设置请求的URL和其他选项
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_ENCODING, 'UTF-8');

// 设置要发送的数据
$data = array(
    'message' => utf8_encode('Bonjour le monde')
);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

// 执行请求并获取响应
$response = curl_exec($ch);

// 检查是否有错误发生
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}

// 关闭CURL资源
curl_close($ch);

// 处理响应数据
echo $response;
