---------
The [] operator of String returns a PChar....what the hell ich a PChar? Is is not documented in the cinema sdk, and also if I try to do something like this:
string test("asdf");
PChar s = test[1];
if fails, because PChar is not a known type....
At least the [] operator seems to return a valid unicode value, but what about that PChar??? It should be something like an unsigned 32Bit value, right? So would it be ok if I use ULONG instead of PChar? And why cant I use PChar? Even if I look in c4d_string.h, PChar occures...so somehow, somewhere it should be defined?

Hi,

in c4d_string.h:

class String
{
...
     public:
class PChar {...};
...
};

Please test

String test ("hallo");
String::PChar p = test[1];

or use GetCString()

Well...hrm....maybe I really should get some glasses ;)
But one thing I dont understand remains....for the characters there is also used UWORD. What is a UWORD? Is is 16bit or 32bit? 32bit I guess...at least it should be for use with unicode...right?

typedef unsigned short int     UWORD;

i think, this is unicode

unsigned short int?????? This is 16bit! Unicode is 0...D7FF and E000...10FFFF inclusive! It definitely needs 32Bit!!!

many types of unicode exists. I think, Cinema use the 2Byte-Unicode

Hm no....have a look on www.unicode.org, only one type of unicode is defined! There are several possibilities how to store the characters, UTF-8, UTF-16, UTF-32, big endian and low endian variants of it....but the possible range of a character is always 32 Bit!

Hm....seems that the whole windows world only uses 16Bits for unicode chars........in case of doubts, its always the evil microsoft ;)

The current version of Unicode (4.0) does indeed require a 32 bit space for characters, though there are some schemes for fitting this into 16 bit spaces using surrogate pairs. If you need to fit such characters into a String, I suggest you treat it as UTF-16. (The first Unicode version to reserve characters above 16 bits was 2.0, which even predates the addition of the Euro character.)
However, all of this is kind of lame to argue about anyway, since the major bottleneck for full Unicode support in C4D is in the GUI.

Hm, for me it is still important how cinema handles the unicode strings, after a check of our demands I can say that I can live with 16 Bit. For the gui we will have to build some workaround, in a first step we will display our strings as bitmaps, which will be rendered in background, in a second step we want to build a customgui element which will hopefully be able to edit, maybe with some kind of virtual keyboard, or we will call an external editor for our strings.....dirty, but we really need to supply unicode strings to our plugins.
