Querying with Danish characters in SKU returns no results

[kbubandt]

Using Danish characters in an sku query (æøåÆØÅ) results in no hits.
If the same query phrase is used in GraphiQL or Insomnia, the result is positive as expected.

Query:
{ products(first: 1, query: "sku:GR-GREGARTEØ-0100") { edges { node { id } } } }

Result:
{"response":{},"body":{"products":{"edges":[]}},"errors":false,"timestamps":[null,1585393004.7812]}

If same query is run in GraphiQL or Insomnia this is the result:
{
"data": {
"products": {
"edges": [
{
"node": {
"id": "gid://shopify/Product/9628048583"
}
}
]
}
},
"extensions": {
"cost": {
"requestedQueryCost": 3,
"actualQueryCost": 3,
"throttleStatus": {
"maximumAvailable": 1000.0,
"currentlyAvailable": 997,
"restoreRate": 50.0
}
}
}
}

And I really cant figure out why?

Hi I will have to look into this... given its characters like that, I have no idea if this is a core php problem with unicode, guzzle, curl, or something else.

@kbubandt Is this still an issue with the newest version? I believe something internally in Guzzle may have resolved this.

I used that SKU on a test store with good results...

<?php

require 'vendor/autoload.php';

use Osiset\BasicShopifyAPI\Options;
use Osiset\BasicShopifyAPI\Session;
use Osiset\BasicShopifyAPI\BasicShopifyAPI;

$options = new Options();
$options->setVersion('2020-01');

$api = new BasicShopifyAPI($options);
$api->setSession(new Session('-----------.myshopify.com', 'dd69e76588e3058b0b8ae1dd7a7b7dn9'));

$x = $api->graph('{ products(first: 1, query: "sku:GR-GREGARTEØ-0100") { edges { node { id, handle } } } }');
print_r($x['body']);

Result:
