I'll try my best to answer, tho I'm hardly eligible. According to training instructions (on http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3) and general OCR knowledge, you cannot train solely by new characters. You need training images, you need to create boxes (with any box editor, but I only used Qt Box Editor). Once you create new boxes around your new tiff image, and label them accordingly, you should be ready for training.
Keep in mind, you'll need at least 12 low x-height in pixels (preferably around 20 pixels), variety in images would be nice for increased performance. Follow training instructions, train your own language file, try OCR again, if you fail again, I'm sure someone else who has wider knowledge than me should be able to answer your further questions.
