This thread is resolved. Here is a description of the problem and solution.
Problem: I can only see ??????? instead of my text on some strings.
Solution: That usually happens when you use the wrong alphabet on languages that do not accept them (like chinese characters on a russian locale, etc). Please go to WPML > Languages and make sure you have the right locale and code for your language.
