Question

How to convert a CGPDFStringRef to unicode char? I have used CGPDFStringCopyTextString to get the string and then [string characterAtIndex:i] to cast to unichar, is this the right way? or is there any way to get the bytes of the string and convert to unicode directly?
Need some guidance here.

Answer 1

NSString is capable of handling of unicode characters itself, you just need to convert the CGPDFString to NSString and further you can use it as follows:

NSString *tempStr = (NSString *)CGPDFStringCopyTextString(objectString);
