已设UTF-8编码，网页希腊字符仍显示为问号问题求助

Let’s break down why your Greek characters are appearing as ???? and fix this issue step by step:

1. Fix Eclipse’s File Encoding Settings #

The most common culprit here is that Eclipse might be saving your files in a non-UTF-8 encoding, which mangles Greek characters:

• Right-click your HTML/JS files in Eclipse → Properties
• Navigate to the Resource tab
• Change Text file encoding from "Default" to UTF-8 (select "Other" and pick UTF-8 from the dropdown)
• Save the settings—note that any already corrupted characters (like the ����� in your code) can’t be recovered, so you’ll need to retype the Greek text.

2. Replace Corrupted Greek Text in HTML #

Your HTML headers and table headings are already garbled. Replace them with proper Greek characters:

<!DOCTYPE html> 
<html lang="el"> <!-- Set language to Greek for better browser compatibility -->
<head> 
    <meta charset="UTF-8"> 
    <meta name="viewport" content="width=device-width, initial-scale=1.0"> 
    <meta http-equiv="X-UA-Compatible" content="ie=edge"> 
    <title>Προϊόντα</title> <!-- Greek title -->
</head> 
<body> 
    <form role="form" name="insertForm" accept-charset="utf-8"> 
        <h2><b>Προσθήκη Προϊόντων</b></h2> 
        <div> 
            <table style="width:100%;"> 
                <thead> 
                    <tr> 
                        <th style="width:140px;">Κατηγορία</th>
                        <th style="width:305px;">Περιγραφή</th>
                        <th style="width:250px;">Λεπτομέρειες</th>
                        <th style="width:75px; ">Τιμή (€)</th>
                        <th></th> 
                    </tr> 
                </thead> 
                <tbody ng-repeat="x in product track by $index"> 
                    <tr> 
                        <td><input style="width:140px;" type="text" value="{{x.Category}}" /></td> 
                        <td><input style="width:305px;" type="text" value="{{x.Description}}" /></td> 
                        <td><input style="width:250px;" type="text" value="{{x.Details}}" /></td> 
                        <td><input style="width:75px;" type="number" value="{{x.Price}}" /></td> 
                        <td><input type="button" ng-click="removeProduct($index)" value="Αφαίρεση" /></td> <!-- Greek button text -->
                    </tr> 
                </tbody> 
            </table> 
        </div> 
        <hr> 
    </form>
</body>
</html>

3. Fix Garbled Comments in JavaScript #

Your JS code has corrupted comments referencing the input fields. Update those to use correct Greek text:

var product = $scope.product = []; 
$scope.addProduct = function () { 
    var product = {}; 
    product.Category = $scope.Category; 
    product.Description = $scope.Description; 
    if (!!$scope.camForm.fields[0].element[0].files[0]) { 
        product.Details = $scope.camForm.fields[0].element[0].files[0].name; 
    } else { 
        return; 
    } 
    product.Price = $scope.Price; 
    $scope.product.push(product); 
    $scope.Category = ""; // We clear the TextBox "Κατηγορία".
    $scope.Description = ""; // We clear the TextBox "Περιγραφή".
    $scope.Details = ""; // We clear the TextBox "Λεπτομέρειες".
    $scope.Price = ""; // We clear the TextBox "Τιμή".
}; 
$scope.removeProduct = function (index) { 
    var category = $scope.product[index].Category; 
    $scope.product.splice(index, 1); 
} 
$scope.isAddFormValid = function () { 
    return ($scope.Category && $scope.Description && $scope.camForm.fields[0].element[0].files[0] && $scope.Price) ? true : false; 
} 
camForm.on('form-loaded', function() { 
    camForm.variableManager.createVariable ({ 
        name:'product', 
        type:'json', 
        value:product 
    }); 
}); 
camForm.on('submit', function(evt) { 
    if (product.length<1) { 
        evt.submitPrevented = true; 
    } 
});

4. Quick Validation Check #

• If you’re testing locally, open your browser’s dev tools (F12) → Network tab, and verify that your HTML file’s Content-Type response header includes charset=UTF-8.
• If deploying to a server (like Tomcat), ensure the server is configured to serve files with UTF-8 encoding.
