1 | /* |
| 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. | |

| 25 | * an initial draft of the mapping table. | |
