UNICODE support

Hello All
I am downloading one file from web having encoding UTF-8 ( Unicode Support ). After downloading , I am reading the file into buffer in CString.But when I saw the buffer I found that there are some unidentified characters ( Looks like empty spaces but not spaces ). I am getting the same buffer though I converted it into UNIOCODE using MultiByteToWideChar.
like this
MultiByteToWideChar( CP_ACP, 0,str,strlen(str)+1, wszStr,256 );  

NOw what can I do to see those unidentified characters ?  If not possible , How can I remove those characters ?
Thanks in advance.

basically problem is that, basic display can't have basic Unicode support ,that why you are see ing the that boxes etc.

 now for removing these character you have to compare each character with ascii character set ie check ascii value each character .
hope this will work

if the source is utf8, you should pass CP_UTF8 to MultiByteToWideChar

MultiByteToWideChar( CP_UTF8, 0,str,strlen(str)+1, wszStr,256 );  
look up msdn to see return value of MultiByteToWideChar, your buffer may be too small.
