Unicode is a character encoding that aims to represent every writing system that has ever been used.
Beginning with NetHack 3.7.0, the map can be configured to display any Unicode character to represent most map symbols - many writing systems will be of little use to NetHack, but the extensive inventory of accented Latin letters and symbols should prove quite useful. With an appropriate font mapping to the Private Use Areas, a Unicode-enabled map could in principle display tiles in the TTY and Curses ports.
The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.
Unicode support is still incomplete.Current state of support
Unicode symbols are supported in the platforms and window ports indicated in the table below.
| Window port | Platform | Support | Notes |
|---|---|---|---|
| TTY | Linux and Mac | Yes | |
| TTY | Windows | Yes | |
| TTY | MS-DOS | Yes | |
| Curses | Linux and Mac | Yes | |
| Curses | Windows | No | |
| Curses | MS-DOS | Yes | If WANT_DOSVGA is specified at build time |
| Win32 | Windows | No | |
| Qt | Windows, Linux and Mac | No | |
| X11 | Linux and Mac | No |
How to configure
The file "symbols" contains several configurations for the map. In the supplied configuration, "Enhanced1" specifies Unicode characters.
A character may be specified using this form:
S_vwall: U+2502
The quoted form used for other symbol types is not supported.
One may specify a symbol for a specific monster as follows:
G_female_giant_ant: U+E000
One glyph symbol is defined for every glyph code. About half of these codes can never occur; the largest reason is that eight glyphs are allocated for swallow attacks for each monster, but only a few monsters can swallow.
Color can be assigned to each glyph:
G_female_giant_ant: U+E000/200-100-50
The numbers are intensity for red, green and blue, ranging from 0 to 255
Outstanding bugs
- Not all configurations support Unicode, and many that do support it do not support full color.
- All configurations in "symbols" that declare Unicode get parsed as a single configuration.
- Many configured symbols may cause delays in starting the program.
- Symbols for objects are accepted but not displayed. The default ASCII characters appear instead.
- The --dumpglyphids is not supported on all platforms.
