Objective-C: unichar vs. char

Question

I'm a little confused between a unichar and a char. Can I treat unichar's similar to char's?

For example, can I do this:

-(BOOL)isNewLine:(unichar)c {  if(c == '\n')   return YES; else   return NO;  } 

Answer 1

Yes, unichar is internally unsigned short, so you can meaningfully compare it with a char (if the latter is ASCII, but that works fine for '\n').
