Error in begining a session when using UTF16 mode in OCIEnvNlsCtreate

Question

I wrote this code :
OCIEnv* envhp;
OCIError* errhp;
OCIServer* srvhp;
OCISvcCtx* svchp;
OCISession* usrhp;
envhp = (OCIEnv *) 0;
errhp = (OCIError *) 0;
srvhp = (OCIServer *) 0;
svchp = (OCISvcCtx *) 0;
usrhp = (OCISession *) 0;
int mode = OCI_DEFAULT;
char* dblink=/* DBLINK */;
     sword status;
OCIEnvNlsCreate ( &envhp, (ub4) mode, (dvoid *)0,(dvoid*(*)(dvoid ctxp, size_t size))0,(dvoid(*)(dvoid ctxp, dvoid memptr, size_t newsize))0,(dvoid (*)(dvoid ctxp, dvoid memptr))0,(size_t)0, (void **)0, (ub2)OCI_UTF16ID, (ub2)OCI_UTF16ID);
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&errhp, (ub4)OCI_HTYPE_ERROR,(size_t)0, (dvoid**)0);
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&srvhp, (ub4)OCI_HTYPE_SERVER,(size_t)0, (dvoid**)0);
status = OCIServerAttach(srvhp, errhp, (text*)dblink,(sb4)strlen(dblink), (ub4)OCI_DEFAULT);
if (status != OCI_SUCCESS)
return 0;
char username = /username*/;
char password = /password*/;
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&svchp, (ub4)OCI_HTYPE_SVCCTX,(size_t)0, (dvoid**)0);
OCIAttrSet((dvoid*)svchp, (ub4)OCI_HTYPE_SVCCTX, (dvoid*)srvhp, (ub4)0,(ub4)OCI_ATTR_SERVER, errhp);
OCIHandleAlloc((dvoid*)envhp, (dvoid**)&usrhp, (ub4)OCI_HTYPE_SESSION,(size_t)0, (dvoid**)0);
OCIAttrSet((dvoid*)usrhp, (ub4)OCI_HTYPE_SESSION, (dvoid*)username,(ub4)strlen(username), (ub4)OCI_ATTR_USERNAME, errhp);
OCIAttrSet((dvoid*)usrhp, (ub4)OCI_HTYPE_SESSION, (dvoid*)password,(ub4)strlen(password), (ub4)OCI_ATTR_PASSWORD, errhp);
status = OCISessionBegin(svchp, errhp, usrhp, OCI_CRED_RDBMS, (ub4)OCI_DEFAULT);
When I use OCI_UTF16ID in OCIEnvNlsCreate it gives me an error in OCISessionBegin. But when I use 871(utf8) instead it works properly. Why does this happen? How can I work whit OCI_UTF16ID?

Re: OCIObjectSetAttr() and UTF16 environnement might be of interest, even though it's a little different. Still relates to UTF16 though. --DD
