At the beginning of times the macro X and S, simply call a class which allocate and , more important, free the memory allocate by the translate call, nothing more, nothing less, than the way show by a lot of examples or tutorial about xerces Now I added more core to manage the character wich require more than 7 bit, a strangely anough , it seems to work. I supposed that already exist a better way to do that so I post my revision of this class, so, mybe , it should be improved , or some suggestions will come about that.
BTW I didn't understood where and how use the XMLCh array ( XMLCh xmlStr[] =
{ '(', 0xA5, ')', chNull };). please can you provide me some example if you
have someone ?

Oggetto: RE: R: R: R: using non standard character with zerces
I should know better than to just ape other people's code without
understanding it. What does the X() macro or function do?
It's starting to sound like the problem is your compiler's wide character
support (if any). Does your compiler have support for strings of characters
with more than 7 bits? If not, you'll probably have to create XMLCh arrays
rather than native strings. If you put the following XMLCh string into your
DOM, you should get a parenthesized yen symbol in the output:
XMLCh xmlStr[] = { '(', 0xA5, ')', chNull };
If you need cross-platform portability, this is definitely the way to go.
If you look in XMLUni.cpp, you'll see dozens of strings defined this way
precisely because compiler support for wide character strings is quite
variable.
