How can I get the example fonts from the font file Programmatically?

Question

Hi Friends,
         I am doing one mac application for the fonts management. Now I would like to Preview the Font in the NSTextView.  This is my coding for the textView.
    NSTextView *text3=[[NSTextView alloc]initWithFrame:NSMakeRect(250,500,450,30)];
    [text3 setString:@"ABCDEFGHIJKLMNOPQRSTUVWXYZ"];
    [text3 setFont:[NSFont fontWithName:@"GangofThree" size:40]];
    [[[self window] contentView] addSubview:text3];
Because I have set the string in English for the NSTextView I can't able to view the other languages characters.I got the character set of the font file by using this code.
   NSCharacterSet *characterset = (NSCharacterSet *) CTFontCopyCharacterSet (fontRef);
This Font is greek font.Now My question is how can I able to get the greek characters from this characterset.

Your text string would certainly have to be in Greek itself, not Latin.  No normal font just translates Latin letters to Greek, they use other codepoints reserved for Greek letters.
