+ * 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
+ * keysym2ucs() maps a keysym onto a Unicode value using a binary search,
+ * therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * The keysym -> UTF-8 conversion will hopefully one day be provided
+ * by Xlib via XmbLookupString() and should ideally not have to be
+ * done in X applications. But we are not there yet.
+ *
+ * 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.
+ *
+ * NOTE: The comments in the table below contain the actual character
+ * encoded in UTF-8, so for viewing and editing best use an editor in
+ * UTF-8 mode.
+ *
+ * Author: Markus G. Kuhn <mkuhn@acm.org>, University of Cambridge, April 2001
