Converting to Unicode?

[Bob]

I am writing a Carbon app that needs to convert to unicode from other
encodings. I get the feeling that there are many messy old ways to do this
and newer ways. Where should I be looking? In TextEncodingConverter.h? Or is
there something better?

There seems to be a mountain of documentation about this subject. If someone
could cut through the fog and tell me where to look, I would appreciate it.

If it is possible I want to convert a string of bytes from from EUC-JP to
UTF-16.


In TextCommon.h I found this define - it looks like what I want:

kTextEncodingEUC_JP = 0x0920,
/* ISO 646, 1-byte katakana, JIS 208, JIS 212*/



Then for UTF-16 there are these??:

kTextEncodingDefaultFormat = 0, /* Formats for Unicode & ISO 10646*/
kUnicode16BitFormat = 0,


Am I on the right track?

Thanks.

Something like this should work:

CFStringRef str;
str = CFStringCreateWithBytes(kCFAllocatorDefault, myEUCJPBytes,
numBytes, kCFStringEncodingEUC_JP, false);
if (str != NULL) {
// Managed to create the string successfully
CFIndex length = CFStringGetLength(str);
UniChar *chars = (UniChar *) malloc(length * sizeof(UniChar));
CFStringGetCharacters(str, CFRangeMake(0, length), chars);

// We don't need this any more
CFRelease(str);

// Now chars is the UTF-16 data that corresponds to the
// original bytes.
....
}

Hope this helps,
Eric
