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. + * + * Author: Markus G.
