Try making a file named spa.user-words in tesseract-ocr/tessdata with this line in it: C.V.
This will tell tesseract that this is a special word that it should also look for. You can also add more words on each line in order of the frequency they appear in your context. This feature was added so you can add your-context-specific words to Tesseract's dictionary without having to retrain it.
