Квадратики в терминале

[AlYuSed]

Вроде бы банальная проблема, но я ничего толком не нагуглил. Либо устаревшие советы времен ядра 2.x (танцы вокруг koi-8 и все такое), либо советы про обычный терминал (а не графический, из XFCE), либо совет не работает.



LANG=ru_RU.utf8
В файле rc.font прописано setfont -v ter-v22b
Попытка написать то же самое в терминале XFCE выдает ошибку: Не удалось получить файловый дескриптор, указывающий на консоль

Что делать и кто виноват?

Что делать и кто виноват?

Nobody's to blame but for Russian the right font is ter-k22b. I just checked, all characters are properly rendered then.

See /usr/doc/terminus-font-4.40/README to know more.

And xfce4-terminal is right, terminus fonts are in PSF format intended for the Linux console, not suitable under X. Try a DejaVu font instead, whatever.

PS Sorry I don't speak Russian and my native language is French, so I answer in English.

It's just an idiom.

but for Russian the right font is ter-k22b. I just checked, all characters are properly rendered then.

KOI-8R is obsolete. Apparently, the man pages are written using this encoding, that's why I have everything well displayed in Russian, apart from them. As a quick and dirty solution I do this: LANG=C man slapt-get

And xfce4-terminal is right, terminus fonts are in PSF format intended for the Linux console, not suitable under X. Try a DejaVu font instead, whatever.

Russian letters are displayed normally with Terminus, but not in the man pages. The only difference is that now man pages do not display the squares, but the question marks.

I think I'll just switch the system language to English. I freely read technical English, so it is comfortable for me. Besides, this is not the only inconvenience. For example, folders in the home directory are created with Russian letters. They are displayed normally in the console and in GUI, but it is inconvenient: I have to switch from English keyboard layout to Russian and vice versa. But we are lazy slackers, right?

KOI-8R is obsolete.

It is not obsolete at all. It is just not intended for an X terminal, but only for a Linux console. And it is indeed suitable for Russian as it includes all the needed glyphs.

You can check that: just type in a Linux console (not in xfce4-terminal)

Code: Select all

showconsolefont

to display all glyphs included in the loaded font.

Apparently, the man pages are written using this encoding, that's why I have everything well displayed in Russian, apart from them.

No. the man pages are written in UTF-8 encoding but the Terminus fonts include an UTF-8 table that maps the Unicode code point of a given character to its legacy 8-bits encoding, in this specific case KOI8-R.

This is necessary because a plain Linux console can display only a set of 256 character at any given time.

To overcome this limitation, you would need to use instead a framebuffer terminal like fbterm.

As a quick and dirty solution I do this: LANG=C man slapt-get

Not a solution at all.

Russian letters are displayed normally with Terminus, but not in the man pages. The only difference is that now man pages do not display the squares, but the question marks.

Again Terminus fonts are not intended for an X terminal at all.

The solution is to just setup correctly xfce4-terminal. I will refer to Terminal's menu in English.

1) Click Edit => Preferences => Appearance and choose for instance the font "DejaVu sans Mono Book" with the size you prefer.
2) Click Terminal => Set Encoding and choose "Default (UTF-8)"

If I do that, then start Terminal with LANG set to ru_RU.utf8 and type "man slapt-get", here is what I get:

Это только в MAN? Попробуй в /etc/man.conf поменять строку "NROFF <что-то там>" на: "NROFF /usr/bin/groff -Dutf8 -Tutf8 -mandoc"

[DidierSpaier]

In ~/.profile in Slint we write

Code: Select all

export GROFF_ENCODING=UTF-8

I think that the same setting is made in Salix (maybe in another file like ~/.bashrc or ~/.bash_profile, I don't remember exactly).

Поменял, эффекта нет.

I think that the same setting is made in Salix (maybe in another file like ~/.bashrc or ~/.bash_profile, I don't remember exactly).

There has already been written utf8, I changed to UTF-8, but to no avail.

I have a feeling that the cure is worse than the disease. I have already said that for me it is not a problem. I find it easier to change the system language to English.

Давно такого не видел, но в памятках-рецептах проверенных на 13.37 по этому поводу имеется запись...
Советуется содержимое файла /etc/rc.d/rc.font заменить на:

Code: Select all

#!/bin/sh

unicode_start LatArCyrHeb-16
for i in 1 2 3 4 5 6;do
  echo -ne "\033%G" >/dev/tty$i
done

Помечено что помогло, хотя подробностей я уже не помню.

[AlYuSed]

Apparently, the problem is not in the system settings, because some man-pages are displayed correctly.
