i have unicharset with complex value. it's not like in literature on https://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3, it's more than it.

No matter what the documentation says, the source code is the ultimate truth, the best and most definitive and up-to-date documentation you're likely to find.[1] ;-)

Suggested reading for today is unicharset.h[2] unicharset.cpp[3]

this is my sample of my code :

a 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # a [61 ]a

n 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # n [6e ]a

c 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # c [63 ]a

r 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # r [72 ]a

k 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # k [6b ]a

f 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # f [66 ]a

d 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # d [64 ]a

s 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # s [73 ]a

w 3 0,255,0,255,0,32767,0,32767,0,32767 NULL -1 0 0 # w [77 ]a

In past I did "fast" examination[4], but I never find time (reason, priority???) for deeper evaluation of this file. So if anybody has time/resource please feel free to have a look on this and share your experience with community...

Here some hints:

• there could be several version of unicharset file[5]
• some part of data (e.g. ranges, script)  are not fill in by current training tools (e.g. they have default/initted values)
• extracting of unicharset from data files provided by google can help with analyze...
