I am using myTess->TesseractExtractResult(&text, &lengths, &costs, &x0, &y0, &x1, &y1, page_res_pass2) to get the recognized characters separately as well as confidence numbers etc - all is fine, except the returned characters, which seem to include some occasional 2-bytes characters among other, mostly 1-byte characters. I wouldn't mind ignoring all of these characters (which are > 127, i.e. not alpha- numeric ASCII codes) but I am not sure how to properly ignore them: should I treat any char > 127 as a prefix to a double-byte character which includes the next one?
I tried to convert "text" (returned by TesseractExtractResult) into a UTF8 string but that fails on occasion depending on the image scanned. The short question is: where can I find the documentation of the encoding of the text array returned by TesseractExtractResult? Can I set a variable to force single-byte values only? And a related question: it seems TesseractExtractResult returns blanks for either and actual blank or a newline position - in both cases with a rect with +/- maxint (32xxx), and I am left with the task to decide if it is a blank or a newline (based on position of previous char). Any variable to just ask Tesseract to generate blanks or newlines itself? Thanks!
