MFC in the file transfer (MFC own CFtpConnection class), under the Linux GB2312 utf-8, an odd number-CodePudding

. 
Would be * WSTR=new would [len + 1]; 
Memset (WSTR, 0, len + 1);//there's a problem, the length of the memset is byte, WSTR would be double byte need take 2, memset (WSTR, 0, sizeof (would) * (len + 1)); 
. 
Char * tempStr=new char [len + 1]; 
Memset (tempStr, 0, len + 1);//there is no problem, because tempStr is char single-byte 
.

Can changed the above trouble spots, and then send it again to Linux on the right,

This problem, notice, changed, try once, is still the same, there is the code

Would be * WSTR=new would [len + 1];
Memset (WSTR, 0, len + 1);
Utf-8 is usually 3 bytes

Uh huh, can you tell me how to modify? Instead of 3?

Put a little more allowance?

uh-huh, I saw this post, this one is to, but not a go directly to the words, I don't know where is the root cause

can't put a little more allowance?

I can't, I expanded, and the results are the same

CodePudding user response:

To set breakpoints, see first converted UNICODE is correct?
Try CP_ACP code page 936,
MultiByteToWideChar (/* CP_ACP */936,
