this is a question about unicode characters in a text input file. This discussion was close but not quite the answer. Compiled with VS2008 and executed on Windows these charcters are recognized on read (maybe represented as a different symbol but read) - compiled with g++and executed on linux they are displayed as blank.
‚ ƒ „ … † ‡ ˆ ‰ Š ‹ Œ Ž ‘ ’ “ ” • – — ˜ ™ š › œ ž Ÿ
The rest of the Unicode symbols appear to work fine, I did not check them all but found this set did not work.
Questions: (1) Why? (2) Is there a solution?
void Lexicon::buildMapFromFile(string filename ) //map
{
ifstream file;
file.open(filename.c_str(), ifstream::binary);
string wow, mem, key;
unsigned int x = 0;
while(true) {
getline(file, wow);
cout << wow << endl;
if (file.fail()) break; //boilerplate check for error
while (x < wow.length() ) {
if (wow[x] == ',') { //look for csv deliniator
key = mem;
mem.clear();
x++; //step over ','
} else
mem += wow[x++];
}
//cout << mem << " code " << key << " is " << (key[0] - '€') << " from €" << endl;
cout << "enter 1 to continue: ";
while (true) {
int choice = GetInteger();
if (choice == 1) break;
}
list_map0[key] = mem; //char to string
list_map1[mem] = key; //string to char
mem.clear(); //reset memory
x = 0;//reset index
}
//printf("%d\n", list_map0.size());
file.close();
}
The unicode symbols are read from a csv file and parsed for the unicode symbol and an associated string. Initially I though there was a bug in the code but in this post the review found it is fine and I followed the issue to how the characters are handled.
The test is cout << wow << endl;
