oo4o c++ interfaces with unicode

[snailmmx]

Hi all,

The website (www.oracle.com/technology/
tech/windows/ole/htdocs/OO4O_10g_FO.htm ) said that oo4o can support Unicode
now. But in the oracl.h header file, all the strings are still char* type.
Now if I want to write some unicode version applications with c++, will it
be possible to call the functions provided by oo4o without converting the
strings manually?

Thanks.

I don't know oo4o, but in general char* is fine for utf-8 (that's the
whole point of utf-8).

The issue would be whether the string handling functions support utf-8,
and much of the time that doesn't even matter. Many non-utf-8 functions,
e.g. strcmp and strstr, work just fine on utf-8 data, and again, that's
the whole point of utf-8.


char* _could_ be fine for utf-16 also, if the compiler uses 16 bit
characters (like java does). Do any real-world C compilers do this yet?

utf-8 character strings will just take up more space. This is not an
issue of datatype but of memory management.
