modern Linuxes by a patch for UTF-8 console output.
Previously, only BeOS used UTF-8. Tested with:
- the linux console
- xterm
- gnome-terminal
- konsole
- rxvt-unicode
using Fedora 11.
Tested with
- gnome-terminal
- xterm
- konsole
using Ubuntu 9.04
Known "features":
* high intensity colours were actually normal intensity, with a bold attribute set.
This worked fine under gnome-terminal, but xterm didn't have bold versions of all cp437 characters,
which screwed up the window borders in the IDE. And although konsole had them, I didn't like the font -
it converted all the double window borders to a very thick single-line border.
So I disabled the bolding of high intensity colours in all X11 terminals (TERM=xterm)
and replaced it with another ANSI attribute, that actually sets high intensity
colours, but is not (in theory) supported by all terminals. The linux console doesn't
support it - it actually wants a bold attribute, to set high intensity,
so that's why I enabled it only for X11 terminals. All the ones,
that I tried, worked fine (xterm, gnome-terminal,
konsole, rxvt-unicode, also the plain old rxvt, with a non-UTF-8 locale).
* Fedora 11 by default uses a 512-characters font, called latarcyrheb-sun16
for the linux text mode console, which disables the high intensity colours,
effectively reducing the set of available colours to only 8.
This is a hardware limitation of the VGA hardware and can be avoided by
using a 256-character font. It does not need to be cp437,
but it has to have an unicode mapping.
* I haven't tried other linux distros (and unix-like OSes, i.e. FreeBSD and Mac OS X) -
although they should work in theory, they might look bad, due to different fonts, etc.
