I wonder why you don't get the "M" result... what does other ppl get?

Here are my command lines:

Ubuntu
------
ubuntu@ubuntu:~/Desktop$ tesseract a.png a
Tesseract Open Source OCR Engine v3.01 with Leptonica
ubuntu@ubuntu:~/Desktop$ cat a.txt
M

Win7:
----
D:\Tesseract>tesseract a.png a (-psm 7 gives same output)
Tesseract Open Source OCR Engine v3.01 with Leptonica
D:\Tesseract>type a.txt
M

Your image resolution is too low. The command line did produce "M" as output. 
Tried with VietOCR frontend and got correct result.

tested  a.png(which has 96 dpi)in vietocr - displayed correctly.
again tested under r-527 -displayed as "WEE] parental pride"in CMD
again tested under latest version 3.01 displayed "M" eventhough changed from 
96dpi to 200,300 with help of Irfanview, the output was "M" in CMD, If reverted 
to 96dpi from 200,300 it will display as "M" - CMD.

Status changed to "No-longer-an-issue" because input image need preprocessing - 
than ocr works as excpected.
