Yeah, that's a reasonable assumption. >>> I grepped the code and it seems to be looking for something called >>> LANG.user-words, but that didn't seem to do anything -- I got the same >>> garbled text when I ran Tesseract 3 the second time. > > Turns out T3 doesn't even access $LANG.user-words.

I'm toying with the idea of adding support for an actual *user* list - i.e., that tesseract would check $HOME/.tesseract/lang.user-words - because assuming a single user system that the user has full control over is still a braindamaged assumption. >>> phil...@cheetah:~/tesseract/tesseract-ocr-hg-trunk/tessdata$ >>> LD_LIBRARY_PATH=/tmp/tess/lib /tmp/tess/bin/combine_tessdata -u >>> eng.traineddata eng > > [...] >> >> I never got around to playing with that.
