Slashed zeros

Slashed zeros are not recognized correctly, identified as g, 6 or 8?

This can be an issue with the Tesseract language packs.

The following language pack may help to address this issue with slashed zeros:

This can then be used with the IronOCR feature to load custom language packs:

using IronOcr; var Ocr = new IronTesseract();
    Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
    using (var Input = new OcrInput(@"images\image.png"))
    {
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    }
using IronOcr; var Ocr = new IronTesseract();
    Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
    using (var Input = new OcrInput(@"images\image.png"))
    {
    var Result = Ocr.Read(Input);
    Console.WriteLine(Result.Text);
    }

	Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata")
	Using Input = New OcrInput("images\image.png")
	Dim Result = Ocr.Read(Input)
