+/*
+ * Marcus: This code was originally written by Markus G. Kuhn.
+ * I have made some slight changes (trimmed it down a bit from >60 KB to
+ * 20 KB), but the functionality is the same.

+
+/*
+ * 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

+ *
+ * Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
+ * an initial draft of the mapping table.
