I have been investigating the cause of the dictionary files not working for indic script. I looked at the code that creates the dictionary (http://code.google.com/p/tesseract-ocr/source/browse/trunk/dict/trie.cpp) and found that there is no wide character support (wchar_t). It stores one byte per node, and it ends up storing non-printable characters per node. Does this cause the dictionary to be useless for Indic script? I did a very basuc experiment by adding just 2 words in the dawg files. I OCRed the same 2 words from an image, and still got absurd results. I made word_in_dawg function in dict/dawg.cpp execute print_dawg_node for every iteration and it does print correctly for english, but prints a load of garbage characters for Indic. So, will changing all the char to wchar_t and making necessary changes to code of memory alloc solve the problem?
