/* $XFree86$
* This module converts keysym values into the corresponding ISO 10646-1
* (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 0x1000abcd.
*
* 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, June 1999
*
* Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
* an initial draft of the mapping table.
*
* This software is in the public domain. Share and enjoy!
