Please read the complete error message: it's telling you exactly where the problem is.

I think you are using "fancy double quotes" or something like that rather than the normal ones.

Are you doing cut and paste from some word processor? This is probably causing all the errors...

Even though the double quotes look fancy here, its not the case in command prompt. 
From all your help i am able to run this command but still i got lots of thing that says
 
Normalization failed for string  <some character>

and at last with this

Error writing unicharset!!

any help is welcome, i am so new to the tesseract, and trying my way to get in.
