斜線的零無法正確識別，被識別為 g、6 或 8？

這可能是 Tesseract 語言包的問題。

以下語言包可能有助於解決帶斜杠的零的問題：
SlashedZeroOCR

然後可以將其與IronOCR功能結合使用，載入自訂語言套件：
IronOCR中的自訂語言範例

// Import the IronOcr namespace
using IronOcr;

class Program
{
    static void Main(string[] args)
    {
        // Initialize IronTesseract class
        var Ocr = new IronTesseract();

        // Use a custom Tesseract language file, which may help with recognizing slashed zeros
        Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");

        // Specify the OCR input image
        using (var Input = new OcrInput(@"images\image.png"))
        {
            // Perform OCR on the input image
            var Result = Ocr.Read(Input);

            // Output the recognized text to the console
            Console.WriteLine(Result.Text);
        }
    }
}

// Import the IronOcr namespace
using IronOcr;

class Program
{
    static void Main(string[] args)
    {
        // Initialize IronTesseract class
        var Ocr = new IronTesseract();

        // Use a custom Tesseract language file, which may help with recognizing slashed zeros
        Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");

        // Specify the OCR input image
        using (var Input = new OcrInput(@"images\image.png"))
        {
            // Perform OCR on the input image
            var Result = Ocr.Read(Input);

            // Output the recognized text to the console
            Console.WriteLine(Result.Text);
        }
    }
}
