 * This function maps keysyms to QChars exploiting as long as possible the

 * less than 0x100 or larger than 0x01000100, it calculates the
 * corresponding Unicode value and returns the corresponding QChar.
 * Otherwise, it looks the keysym up in the symbolMap, and if it is found
 * it returns the QChar, otherwise the null QChar.
 *
 * Note that symbolMap is lazily initialised only the first time it is
 * needed, so on advanced X implementations that do away with all old-age,
 * non-Unicodish keysyms the map initialisation will never waste CPU time.
