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);
}
