*/
/*
* This module converts keysym values into the corresponding ISO 10646
* (UCS, Unicode) values.
*
* The array keysymtab[] contains pairs of X11 keysym values for graphical
* characters and the corresponding Unicode value. The function
* _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
* search, therefore keysymtab[] must remain SORTED by keysym value.
*
* We allow to represent any UCS character in the range U-00000000 to
* U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
* This admittedly does not cover the entire 31-bit space of UCS, but
* it does cover all of the characters up to U-10FFFF, which can be
* represented by UTF-16, and more, and it is very unlikely that higher
* UCS codes will ever be assigned by ISO. So to get Unicode character
* U+ABCD you can directly use keysym 0x0100abcd.
*
* Original author: Markus G. Kuhn <mkuhn@acm.org>, University of
