RE: Problem converting the Unicode character (U2225) to SJIS

[George R. <gr...@us...>]

Please use this line instead (remove the reference from status).

int32_t len = ustr.extract( pCharBuffer, ustr.length() * 2 + 1, conv, 
status);

Now I have a new problem. I got the following compile error while I was
trying to use
int32_t UnicodeString::extract(char *dest, int32_t destCapacity,
UConverter *cnv,
UErrorCode &errorCode) const;

H:\ICU\others\test\test.cpp(24) : error C2664: 'void __thiscall
icu_2_2::UnicodeString::extract(long,long,unsigned short *,long) const' :
cannot convert parameter 1 from 'char *' to 'long'
This conversion requires a reinterpret_cast, a C-style cast or
function-style cast
Error executing cl.exe.

What did I do wrong? Here is my testing code:

#include <windows.h>
#include <stdio.h>
#include <unicode/unistr.h>
#include <unicode/ustring.h>
#include <unicode/ucnv.h>

int main(int argc, char* argv[])
{
UChar ch = 0x2225;
UnicodeString ustr(ch);

char* pCharBuffer = new char[ustr.length() * 2 + 1];

UConverter* conv;
UErrorCode status=U_ZERO_ERROR;

conv = ucnv_open("ibm-943_P14A-2000", &status);
ucnv_setFallback(conv, TRUE);

int32_t len = ustr.extract( pCharBuffer, ustr.length() * 2 + 1, conv,
&status );  //line 24 where the error is.

len=ucnv_fromUChars(conv, pCharBuffer, ustr.length() * 3 + 1, &ch, 1,
&status);

ucnv_close(conv);

delete[] pCharBuffer;

return 0;
}

You could also keep the converter around instead of closing it.
Extract would open and close a new one which is actually (slightly)
more expensive.

hope this helps.
