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.
