Chapter 7. Output to Display

64

  Fonts with fixed sizes are used. The unit of the width of the font is called 'column'. 'Dou 

blewidth' fonts, i.e., fonts whose width is 2 columns, are used for CJK ideograms, Japanese

Hiragana and Katakana, Korean Hangul, and related symbols. Combined characters used

for Thai and so on can be regarded as 'zero' column characters.

7.1.1 Encoding

Softwares running on the console are not responsible for displaying. The console itself is respon 

sible. There are consoles which can display encodings other than ASCII such as

kon in kon2 package EUC JP, Shift JIS, and ISO 2022 JP

jfbterm EUC JP, ISO 2022 JP, and ISO 2022 (including any 94, 96, and 94x94 coded character sets

whose fonts are available)

kterm EUC JP, Shift JIS, ISO 2022 JP, and ISO 2022 (including ISO8859 {1,2,3,4,5,6,7,8,9}, JISX 0201,

JISX 0208, JISX 0212, GB 2312, and KSC 5601)

krxvt in rxvt ml package EUC JP

crxvt gb in rxvt ml package CN GB

crxvt big5 in rxvt ml package Big5

cxtermb5 in cxterm big5 package Big5

xcinterm big5 in xcin package Big5

xcinterm gb in xcin package CN GB

xcinterm gbk in xcin package GBK

xcinterm big5hkscs in xcin package Big5 with HKSCS

hanterm EUC KR, Johab, and ISO 2022 KR

xiterm and txiterm in xiterm+thai package TIS 620

xterm UTF 8

However, there are no way for a software on console to know which encoding is available. I think

it is a responsibility for a user to properly set LC_CTYPE locale (i.e. LC_ALL, LC_CTYPE, or

LANG environmental variable). Provided LC_CTYPE locale is set properly, a software can use it

to know which encoding to be supported by the console.
