Hi, version of the ambigs file for tesseract 3.00 is 'v1' (it means that next version can bring another version of ambigs file with new format/features). In ccutil/ambigs.cpp I found only one test for version (>0) : it is connected to meaning of last column...
If you want to play/create you own lang.unicharambigs maybe it would be
good to use these variables:
global_ambigs_debug_level 1
global_tessedit_ambigs_training true
it will produce some additional informations.
Concerning UTF-8 I tried to do quick test but I was not able to create
image with mistake in utf-8 letter (tesseract made mistake only on ascii
letter ;-) ). But it make one mistake:
„
interpreted as:
,,
When I created unicharambigs like this:
v1
2 , , 1 „ 1
Than tesseract recognize „ correctly in output („ is utf-8).
So maybe issues regarding utf-8 are solved in lang.unicharambigs.
However, you should make own (more extensive) tests for Kannada or
Indic lang.
