I have installed Tesseract 5.2.0 on Macbookpro (M1 Apple Silicon) running MacOS 12.6.1 Monterey using Homebrew.
I have downloaded IAST.traineddata. Moving this file into /opt/homebrew/cellar/tesseract/5.2.0/share/tessdata or /opt/homebrew/opt/tesseract-lang/share/tessdata doesn't seem to work. I get error messages. How do I load it into the program and use it for OCRing IAST diacritics? Also is there any traineddata files for ISO15919 diacritics? or for Indian Grantha script?
