NetHack Development Team Polls Community For Advice On Unicode

An anonymous reader writes After years of relative silence, the development team behind the classic roguelike game NetHack has posteda question: going forward, what internal representation should the NetHack core use for Unicode characters? UTF8? UTF32? Something else? (See also: NH4 blog, reddit. Also, yes, I have verified that the question authentically comes from the NetHack dev team.)

Use utf if you must, for character names, only.

I started playing nethack before it was nethack, it was just hack. (I may well hold the record for longest time playing without an asencion, but that is beside the point.) I have played other roguelikes and keep coming back to nethack because it is the only one that keeps that same feel for me. It has had the same overall look my entire life. While the expanded character set in UTF would allow for significantly more characters to be used in drawing the map, and designating each monster with a different character, I beg of you not to do so. Keep the overall look the same, (or allow it as a compile time option at the very least) and just use UTF for the character name.

For which implimentation of UTF to use, I'd go with utf8 as it seems to have the widest adoption, or 32 because that will probably allow you the longest time before having to think about this again. I would avoid the middle ground.

UTF-8

UTF-8 is easily adopted by C based software like Nethack because null-terminated string logic works unmodified; a UTF-8 string has no embedded nulls to trip up any code that that measures string length by searching for a zero byte. For the most part things should "just work." UTF-16 and 32 strings have zero bytes embedded among characters, so you have to audit every bit of code to ensure compatibility.
