Summary: 0003728: Graphical glitches with new characters
Description: I'm getting several glitches with the new characters being used to represent trees, water, lava etc. They fall into two categories, and I've included a screenshot of each:

1) Artefact portions of the glyphs used appearing on other tiles which should be empty, or contain another character.

2) Overlapping glyphs

This may of course be my OS? I am running Ubuntu Hardy Heron, and:


$ uname -a
Linux asterion 2.6.24-28-generic #1 SMP Fri Feb 11 17:36:45 UTC 2011 i686 GNU/Linux

My console is a gnome terminal running bash.

For some reason shallow water isn't represented, but it still exists. Weird
movement problems happen when I enter the shallow water. This also happens
consistently in the tutorial.

Version: Dungeon Crawl Stone Soup 0.8.0-a0-6187-geffd6b6 with Console.

OS: Source Mage GNU/Linux, Bash v4.1, xterm v255.

Bisecting between tags 0.7.2 and 0.8.0-a1, I have found the first bad commit.

git output as follows, since I don't know how to read all of the git output (mainly the last line):


a975bb5545e51090570127d9d733d61ae6788b2b is the first bad commit

    Make cset overrides more sane.

    You don't need to specify the charset anymore, save for cset_ibm and
    cset_dec which are for compatibility with legacy config files.

    You can even use cset_ibm without char_set=ibm, it will work.

While this is a known bug in gnome-terminal, it happens only when it has to borrow a character from some other font. And that is why the defaults are chosen from a narrow set that is present in fonts shipped with all major platforms.

I installed Ubuntu, both current and ancient (BTW, hardy has long since lost security support, you'd better upgrade), and trees are just fine. Screenshot with maverick and hardy side-to-side attached.

Which font do you use? Ubuntu's default, DejaVu Mono Sans, has a pretty wide glyph coverage, and doesn't show such problems.

Ah, OK. I'm using Inconsolata, which isn't a standard font. Problem understood, thanks for looking into it.

Inconsolata seems to be one of better fonts around. Heck, I'm personally using Consolas it was based on.

I've just sent its author a request to include this character.

However, since the core bug lies elsewhere, and it works correctly with default settings, let's close this in Crawl.
