macOS Problem with string encoding

[sandeepac]

Sir

I have a problem with encoding of strings

strcpy(myCString, [MyNSString cStringUsingEncoding:NSUnicodeStringEncoding ]);

CFStringRef str1 = CFStringCreateWithCString(NULL,myCString,kCFStringEncodingUnicode);
NSLog((NSString*)str1);

if my unicode string is मनज मानमान मानमा.
then i am getting Only मनज as output.
can you please help me to solve this problem.


Thanking you

Sandeep

Try changing your logging code to

NSLog(@"%@", str1);

and see if you get the expected string back.

Still the Result is Same ............

strcpy(myCString, [MyNSString cStringUsingEncoding:NSUnicodeStringEncoding ]);

CFStringRef str1 = CFStringCreateWithCString(NULL,myCString,kCFStringEncodingUnicode);

That cannot possibly work. C strings are for strings using 8 bit characters. NSUnicodeStringEncoding uses the 16 bit Unicode encoding. As soon as you have a character with a Unicode value from 0 to 255, strcpy () sees a zero byte and thinks that is the end of the string. Same if you have a character with a Unicode value like 256, 512, 768 and so on.

You need to use the appropriate UTF8 encodings. UTF8 encodes Unicode in eight bit values in a way that is compatible with C string functions.

In this case, the whole conversion is not needed anyway. Go to http://www.developer.com and look for "toll free bridging". Might save you lots of work and code and memory and execution time and problems when you mix Cocoa and Core Foundation.
