As my sibling poster mentioned, these are generally research level tasks. Most people working on this are either writing papers on very particular issues related to OCR or they are working in industry and the companies are not open sourcing their code because it is expensive to produce and/or they have custom data sets they don't want to give away. There might be some tutorials somewhere though. Source: previously worked on OCR systems for European and East Asian languages.
