Thank you  very much for  your explanation. So,  at the moment,  I don't
have any choice but to  use XStringToKeysym() which is a bit embarassing
because the  ported code will  still depend on  Xlib for this  call, but
well, I hope someone will fix  this soon because unfortunately I have no
idea how to do it myself...
