The Ubuntu wordlist is pretty big... 921 user-added words...
As wordlists go, that's tiny :)
Aye, but it's an exceptions list :)
Seems to contain a lot of fairly technical words and abbreviations which
I assume aren't in the Tesseract base wordlist.
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 suspect it's
looking for it in the traineddata file...

I never got around to playing with that. I'll have a look at it,
either later, or tomorrow.
Turns out the issue is that combine_tessdata wants the prefix to end
with a period. So 'eng' crashes it, but 'eng.' works fine (and produces
a bunch of files in the CSD).
Lots of new features, lots of new bugs.
Ain't it always the way...
I can scan a few more issues of the journal in question -- as I said
previously, I've got the full run from 1974 through present (with 1990
onwards on DVD), and every issue up to about 1976 uses a table of contents
with a similar format.
Cool, thanks.
No problem. I just need to clear some space on the table and set the
scanner up first...

The adaption step used to be here. It has been moved to after
make_reject_map so that we know whether the word will be accepted in the
first pass or not. This move will PREVENT adaption to words containing
double quotes because the word will not be identical to what tess thinks
its best choice is. (See CurrentBestChoiceIs in
danj/microfeatures/stopper.c which is used by AdaptableWord in
danj/microfeatures/adaptmatch.c)

I must confess I'm not 100% sure what that means...
Thanks,
