-  // is no native event or no better way to get the character.
-  // For example, if a virtual keyboard implementation can only generate key
-  // events with key_code and flags information, then there is no way for us to
-  // determine the actual character that should be generate by the key. Because
-  // a key_code only represents a physical key on the keyboard, it has nothing
-  // to do with the actual character printed on that key. In such case, the only
-  // thing we can do is to assume that we are using a US keyboard and get the
-  // character according to US keyboard layout definition.
-  // If a virtual keyboard implementation wants to support other keyboard
-  // layouts, that may generate different text for a certain key than on a US
-  // keyboard, a special native event object should be introduced to carry extra
-  // information to help determine the correct character.
-  // Take XKeyEvent as an example, it contains not only keycode and modifier
-  // flags but also group and other extra XKB information to help determine the
-  // correct character. That's why we can use XLookupString() function to get
-  // the correct text generated by a X key event (See how is GetCharacter()
-  // implemented in event_x.cc).
