Discussion of [NSString NSJapaneseEUCStringEncoding]

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 NSJapaneseEUCStringEncoding]

+ (NSString *)encodedStringWithContentsOfURL:(NSURL *)url
{
    // Get the web page HTML
    NSData *data = [NSData dataWithContentsOfURL:url];

    // response
    int enc_arr[] = {
        NSUTF8StringEncoding,           // UTF-8
        NSShiftJISStringEncoding,       // Shift_JIS
        NSJapaneseEUCStringEncoding,    // EUC-JP
        NSISO2022JPStringEncoding,      // JIS
        NSUnicodeStringEncoding,        // Unicode
        NSASCIIStringEncoding           // ASCII
    };
    NSString *data_str = nil;
    int max = sizeof(enc_arr) / sizeof(enc_arr[0]);
    for (int i=0; i<max; i++) {
        data_str = [
                    [NSString alloc]
                    initWithData : data
                    encoding : enc_arr[i]
