could not encode content to iso-8859-1

could not encode content to iso-8859-1, I was facing this error while I am generating the QR code for the show personal details by scanning the QR. Therefor, the first, I was creating a vCard using the laravel package. you can see in the below function. After all the data appending in the card, that returned data I was adding in the QR code that time error show. but not able to find the solution. what is going wrong?

After a lot's practice, I found the solution, that I have given you below, utf8_decode() using this function I fix your error. I have also shown you how I was doing and to fix this issue what did.

SOLUTION

Using this function I fix my solution.

$iso88591_1 = utf8_decode($utf8);

HOW HAPPENED IN MY CASE ?

I was generating a QR code. in this QR code I was appending my card data by generating form the card.

use QrCode;
use Storage;

$vCardData = raf_create_vcard($data); // MY HELPER FUNCTION

$qr = QrCode::format('png')
    ->merge(asset('public/qr-logo.png'), 0.3, true)
    ->size(200)
    ->errorCorrection('H')
    ->generate($vCardData);

    $name = time().'.png';
    
    Storage::disk('public')->put($name,$qr);

Unique violation: 7 ERROR: duplicate key value violates unique constraint "users_pkey" DETAIL: Key (id)=(1) already exists.

Error :unable to connect to server connection to the server at port 5432 failed timeout expired

This is my function, my name was coming with multiple spaces between my first name and last name. using this function I remove all the extra space between that string and the QR code gets generated.

function raf_create_vcard($data,$type=false){

    // define vcard

    $vcard = new VCard();

    // define variables
    
    $additional = '';
    $prefix = '';
    $suffix = '';

    // THIS PROBLE

    // THIS CREATING PROBLEM WHEN I GENERATING THE QRCODE
    $name = 'Haresh   Chauhan';  // MY NAME COMING SOMETHING LIKE THIS
                                // SO THE QR NOT ACCEPTING THIS NAME WITH MULTIPLE SPACE

    // THIS SOLUTION

    // USING THIS utf8_decode() FUNCTION THE MULTI SPACE REMOVE
    $name = utf8_decode('Haresh   Chauhan');

    // ADD PERSONAL DATA
    $vcard->addName($name,'swapinfoway', $additional, $prefix, $suffix);

    // ADD WORK DATA
    $vcard->addCompany($data['business_unit_name']);
    $vcard->addJobtitle(utf8_decode($data['designation_english']));

    if ($type == true) {

        $vcard->addPhoneNumber($data['mobile_no'], 'WORK');
    }

    $vcard->addPhoneNumber(businessAlias($data['business_unit_name'])->business_unit_tel, 'WORK');
    $vcard->addEmail($data['email_id']);
    $vcard->addURL('http://'.businessAlias($data['business_unit_name'])->business_unit_web);

    // RETURN VCARD AS A STRING
    return $vcard->getOutput();
}
