Re: [tesseract-ocr] recognising roman with sanskrit diacritics
Checked with both light & dark pdfs. The results are very good. Thanks. A few concerns. E is consistently missed in both. J is missed consistently in darker image but recognized as T in dark image. ṝ is recognized as ṛ consistently. Can these be addressed ? I am using tesseract 4 alpha windows build from command line. Are the dev files in repos ?
