Issue when sending Query with Arabic characters through API - api

Question

I can't send Query with Arabic characters through API. I am trying to send the query from CS-Cart to Quickbooks Online.
I tried to send the query using the arabic letters as the following:
select * from Customer Where DisplayName = 'احمد عبدالعزيز'
it returns:
{
"responseHeader": {
"status": 400,
"message": "Bad Request",
"intuitTid": "2dbec1fd-5dc1-3a14-4a12-7c338db0ee2a",
"realmID": "123146420719144"
},
"response": {
"Fault": {
"Error": [
{
"Message": "Error parsing query",
"Detail": "QueryParserError: Invalid content. Lexical error at line 1, column 45. Encountered: \"\\u0627\" (1575), after : \"\\'\"",
"code": "4000"
}
],
"type": "ValidationFault"
},
"time": "2019-07-04T07:09:03.026-07:00"
}
}
And if I try it after encoding the name and send the query as the following:
select * from Customer Where DisplayName = '%D8%A7%D8%AD%D9%85%D8%AF+%D8%B9%D8%A8%D8%AF%D8%A7%D9%84%D8%B9%D8%B2%D9%8A%D8%B2'
it returns nothing:
{
"QueryResponse": {},
"time": "2019-07-04T07:09:42.698-07:00"
}
I am expecting to get like:
{
"QueryResponse": {
"Customer": [
{
"Taxable": false,
"BillAddr": {
"Id": "924",
"Country": "Saudi Arabia"
},
"ShipAddr": {
"Id": "925",
"Country": "Saudi Arabia"
},
"Job": false,
"BillWithParent": false,
"Balance": 157.5,
"BalanceWithJobs": 157.5,
"CurrencyRef": {
"value": "SAR",
"name": "Saudi Riyal"
},
"PreferredDeliveryMethod": "None",
"IsProject": false,
"domain": "QBO",
"sparse": false,
"Id": "577",
"SyncToken": "0",
"MetaData": {
"CreateTime": "2019-07-01T06:37:32-07:00",
"LastUpdatedTime": "2019-07-01T06:37:33-07:00"
},
"GivenName": "Ramil",
"FamilyName": "Gilaev",
"FullyQualifiedName": "Ramil Gilaev",
"DisplayName": "Ramil Gilaev",
"PrintOnCheckName": "Ramil Gilaev",
"Active": true,
"PrimaryPhone": {
"FreeFormNumber": "123456789"
}
}
],
"startPosition": 1,
"maxResults": 1
},
"time": "2019-07-05T02:12:35.562-07:00"
}
Also I noticed even if the Query is in English name, it results the same.
select * from Customer Where DisplayName = 'Ahmed Al-Khuraisir'
it results:
{
"QueryResponse": {},
"time": "2019-07-05T03:31:11.149-07:00"
}
