Hi Diego,
private static int my_string_handler(string str)/*no '*'*/ {
....
}
If possible use unichar, string.next_char, string.get_char, to
manipulate string is better than directly access the char by its
location because all strings are utf8 encoded.
StringBuilder sb = new StringBuilder("");
for(weak string s = str; s.get_char()!=0; s = s.next_char()) {
unichar c = s.get_char();
if(c != '+') sb.append_unichar(c);
else {
....
break;
}
}
