Using different interpolation methods of magnification gave me different results, but I was not able to get the "/" character out of the string. Magnifying the image by 200% using a Box, Triangle, or Catmull-Rom interpolation algorithm gave me "NIA". Using Mitchell, I got "NVA". The Cubic B-Spline was too fuzzy for Tesseract to recognize any of the characters.
Does anyone have any further ideas? I wish there was a way to tell Tesseract to ignore font embellishments, such as italics or underlining.
