8-bit ASCII encoding with NEXTSTEP extensions.

Discussion of [NSString NSNEXTSTEPStringEncoding]

These values represent the various character encodings supported by the NSStringclasses. This is an incomplete list. Additional encodings are defined in String Programming Guide for Core Foundation (see CFStringEncodingExt.h); these encodings can be used with NSString by first passing the Core Foundation encoding to the CFStringConvertEncodingToNSStringEncoding function.

Example of [NSString NSNEXTSTEPStringEncoding]

void MyLog(NSString *format, ...) {
    va_list args;
    va_start(args, format);
    NSString *formattedString = [[NSString alloc] initWithFormat: format
                                                  arguments: args];
    va_end(args);
    [[NSFileHandle fileHandleWithStandardOutput]
        writeData: [formattedString dataUsingEncoding: NSNEXTSTEPStringEncoding];
    [formattedString release];
}

Example of [NSString NSNEXTSTEPStringEncoding]

Example of [NSString NSNEXTSTEPStringEncoding]

CGGlyph* Glyphs = malloc(sizeof(CGGlyph) * [textToDraw length]);
 char* Chars = malloc(sizeof(char) * ([textToDraw length] + 1));
 [textToDraw getCString:Chars maxLength: ([textToDraw length] + 1) encoding: NSNEXTSTEPStringEncoding];

 for(int CurrentChar = 0; CurrentChar < [textToDraw length]; ++CurrentChar)
 {
  Glyphs[CurrentChar] = Chars[CurrentChar]- 29;
 }
