Trying to send email with special characters.

[joaojoyce]

Hi,

The api works great, but when I send an email with some special characters in the subject the result is not perfect.
For instance:

Técnica gets translated to Teìcnica

I'm sending this in the body of the request:

        $message = [
            'subject' => $subject,
            "body" => [
                "contentType" => "TEXT",
                "content"=> $text
            ],
            "toRecipients" => [
                [
                    "emailAddress" => [
                        "address" => $email_to
                    ]
                ]
            ]
        ];

Is there any encoding parameter that I should set?

I'm unable to reproduce this when I run the send mail test: https://github.com/microsoftgraph/msgraph-sdk-php/blob/dev/tests/Functional/MailTest.php#L43. Here's what I see over the wire when I run this:

POST https://graph.microsoft.com/v1.0/me/sendmail

{
    "message": {
        "subject": "2020-08-21 04:57:47",
        "body": {
            "content": "Sent from the SendMail test - T\u00e9cnica"
        },
        "toRecipients": [
            {
                "emailAddress": {
                    "address": "AdeleV@contoso.onmicrosoft.com"
                }
            }
        ]
    }
}

Then when I request this from the service API, I see the following in the response:

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('60ea65d4-ca13-493d-8db8-94ce164cb55a')/mailFolders('sentItems')/messages",
    "value": [
        {
            "body": {
                "contentType": "text",
                "content": "Sent from the SendMail test - T\u00e9cnica"
            }
        }
     ]
}

This is likely not a client or service issue. I suggest that you review your php.ini file and check the internal_encoding and default_charset. It should be UTF-8. Let us know.
