LESSCHARSET = utf-8似乎不起作用 [英] LESSCHARSET=utf-8 less doesn't seem to work

问题描述

我试图在less中查看UTF-8文本文件/流，即使我这样调用它:

I'm trying to view a UTF-8 text file/stream in less, and even if I invoke it like this:

cat file | LESSCHARSET=utf-8 less

与ASCII不兼容的UTF-8字符无法正确显示.取而代之的是，它们的十六进制值在方括号中突出显示，例如<F4>.

the non-ASCII compatible UTF-8 characters don't display correctly. Instead, their hex values appear highlighted in brackets, e.g. <F4>.

使用UTF-8编码在vim中读取相同的文本不会造成任何问题.所以我认为调用less的方式出了问题.

The reading the same text in vim with UTF-8 encoding poses no problems. So I'm thinking something is wrong with the way I'm invoking less.

我的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=

我的次要版本是XCode在OSX Leopard上安装的版本:

My less version is the one installed by XCode on OSX Leopard:

$ less --version | sed 's/^/    /'
less 394

locale -a | grep US | sed 's/^/ /'输出以下内容:

en_AU.US-ASCII
en_CA.US-ASCII
en_GB.US-ASCII
en_NZ.US-ASCII
en_US
en_US.ISO8859-1
en_US.ISO8859-15
en_US.US-ASCII
en_US.UTF-8

推荐答案

1. locale命令输出什么?它是UTF-8语言环境吗?

1. What does the locale command output? Is it a UTF-8 locale?

您确定您的终端设置为显示UTF-8吗? echo -e '\xe2\x82\xac'会产生欧元符号吗?

Are you sure your terminal is set to display UTF-8? Does echo -e '\xe2\x82\xac' produce the € (euro) sign?

您设置的语言环境是否甚至已安装在系统上?是吗 出现在locale -a输出的列表中?

Is the locale that you have set even installed on the system? Is it present in the list that locale -a outputs?

您使用的是哪个版本的less? (运行less --version进行查找.) 真的，真的旧版本甚至不支持LESSCHARSET.这 不太可能是这样，因为我有一个Debian的"sarge"系统， less版本382，如果语言环境为，则甚至不需要LESSCHARSET 正确设置.

What version of less are you using? (Run less --version to find out.) Really, really old versions did not even support LESSCHARSET. This is less likely to be the case, because I have a Debian "sarge" system with less version 382, and it does not even need LESSCHARSET if the locale is set correctly.
