2 * This module converts keysym values into the corresponding ISO 10646
3 * (UCS, Unicode) values.
4 *
5 * The array keysymtab[] contains pairs of X11 keysym values for graphical
6 * characters and the corresponding Unicode value. The function
7 * keysym2ucs() maps a keysym onto a Unicode value using a binary search,
8 * therefore keysymtab[] must remain SORTED by keysym value.
9 *
10 * The keysym -> UTF-8 conversion will hopefully one day be provided
11 * by Xlib via XmbLookupString() and should ideally not have to be
12 * done in X applications. But we are not there yet.
13 *
14 * We allow to represent any UCS character in the range U-00000000 to
15 * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
16 * This admittedly does not cover the entire 31-bit space of UCS, but
17 * it does cover all of the characters up to U-10FFFF, which can be
18 * represented by UTF-16, and more, and it is very unlikely that higher
19 * UCS codes will ever be assigned by ISO. So to get Unicode character
20 * U+ABCD you can directly use keysym 0x0100abcd.
