I noticed "-l lang" before "-psm 0" is missing in your commandline. In the absence of "-l lang" tesseract will always assume as "-l eng".
extract of help is reproduced below: M:\>tesseract.exe -h *Usage:tesseract.exe imagename outputbase [-l lang] [-psm pagesegmode] [configfil* e...] pagesegmode values are: 0 = Orientation and script detection (OSD) only. 1 = Automatic page segmentation with OSD. 2 = Automatic page segmentation, but no OSD, or OCR 3 = Fully automatic page segmentation, but no OSD. (Default) 4 = Assume a single column of text of variable sizes. 5 = Assume a single uniform block of vertically aligned text. 6 = Assume a single uniform block of text. 7 = Treat the image as a single text line. 8 = Treat the image as a single word. 9 = Treat the image as a single word in a circle. 10 = Treat the image as a single character. -l lang and/or -psm pagesegmode must occur before anyconfigfile.
