LESSCHARSET=utf-8 less似乎不起作用

unix utf-8

dan · 技术社区 · 16 年前

我正在尝试在中查看UTF-8文本文件/流 less ,即使我这样调用它:

cat file | LESSCHARSET=utf-8 less

<F4>

使用UTF-8编码读取vim中的相同文本不会带来任何问题。所以我认为我调用的方式有问题 较少的 .

locale 输出如下

LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL=

这是什么意思 locale 命令输出?它是UTF-8语言环境吗?
终端是否设置为显示UTF-8? 做 echo -e '\xe2\x82\xac' 出示(欧元)标志?
在列表中显示 locale -a 输出?
什么版本的 less less --version ) , 真正地 旧版本甚至不支持 LESSCHARSET . 这 较少的 版本382,如果区域设置为

我猜你的文件不是UTF8而是ISO8859(是<F4>字符应该是“”?)

LANG=en_US.ISO-8859-1 xterm . 然后验证区域设置(的输出) locale 应该是类似en_US.ISO-8859-1)的内容。然后使用less查看文件。它显示正确吗?

注意,仅仅使用它是不够的 LESSCHARSET=iso8859 没有启动新的终端。 LESSCHARSET

在Mac OS上,字符集名称必须为大写:

bash-4.4$ less --version
less 458 (POSIX regular expressions)
Copyright (C) 1984-2012 Mark Nudelman

bash-4.4$ LESSCHARSET=cp1251 less
invalid charset name

bash-4.4$ LESSCHARSET=CP1251 less
Missing filename ("less --help" for help)

试试这个命令 file file.txt . 例如,如果输出为“ISO-8859英语文本”,则通过命令将文件编码从ISO-8859更改为UTF-8 iconv -f ISO-8859-1 -t UTF-8 -o testfile.txt file.txt . 如果 less testfile.txt 正确显示,以结束 mv testfile.txt file.txt .

为我工作:

f='path/to/file/filename.extension'; LESSCHARSET=`file -b --mime-encoding ${f}|tr '[:lower:]' '[:upper:]'` less ${f}

less -r 为我正确显示文件。

 -r or --raw-control-chars
              Causes "raw" control characters to be displayed.  The default is
              to  display  control  characters  using  the caret notation; for
              example, a control-A (octal 001) is displayed as "^A".  Warning:
              when the -r option is used, less cannot keep track of the actual
              appearance of the screen (since this depends on how  the  screen
              responds to each type of control character).  Thus, various dis-
              play problems may result, such as long lines being split in  the
              wrong place.
