I am having similar issues as this user had https://github.com/tesseract-ocr/tesseract/issues/305
In my case I'm inputting lines of text containing mostly words with the occasional the use of numbers. Sometimes numbers such as 5 are been confused with the letter s. Is there some settings that can be adjusted to help reduce the frequency of this mistake. Many thanks in advanced -- *Fast Web Media Ltd, Digital World Centre, 1 Lowry Plaza, Media City, Manchester.
