cocoa - Application crashing due to unicode characters in string -


i making application in have store data remote db local sqlite3 db.

problem - when string inserted contains unicode character such as: \u00a0 or \u2022 or \u2019, crashes.

the part of code crashes this-

nsstring *insertquery = @"insert xyz(field1,field2) values (@"1",[recorddict objectforkey:@"field2"]);  // recorddict contains value: @"\u00a0 \u00a0 \u00a0 \u00a0the cadfsdfsdfptain\u2019s" key: @"field2"  sqlite3_stmt *insertstmnt; const char *sql = [insertquery cstringusingencoding:1];  printf("insertquery - %s",sql); // showing insertquery - (null) , crashing @ next line if(sqlite3_prepare_v2(database, sql, -1, &insertstmnt, null) != sqlite_ok){     nslog(@"error while creating insert statement. '%s'",sqlite3_errmsg(database)); }

can suggest me how resolve problem?

thanks,

miraaj

cstringusingencoding: returns null when string cannot losslessly converted specified encoding, hence crash. can use canbeconvertedtoencoding: ensure conversion possible.

furthermore, value 1 corresponds nsasciistringencoding fail string unicode characters. nsutf8stringencoding might more appropriate.
