PHP setlocale,UTF-8与否？

我通过安装了zh_TW语言环境

sudo locale-gen --purge en_US.UTF-8 zh_TW

它的代码集是BIG5

locale: zh_TW           directory: /usr/lib/locale/zh_TW
-------------------------------------------------------------------------------
    title | Chinese locale for Taiwan R.O.C.
    email | bug-glibc-locales@gnu.org
 language | Chinese
territory | Taiwan R.O.C.
 revision | 0.2
     date | 2000-08-02
  codeset | BIG5

我有一个简单的PHP脚本

<?php

putenv('LC_ALL=zh_TW');
setlocale(LC_ALL, 'zh_TW');
bindtextdomain("myPHPApp", "./locale");
textdomain("myPHPApp");

echo gettext("hello");

我准备了一个mo文件(以UTF8格式)并放在

./locale/zh_TW/LC_MESSAGES/myPHPApp.mo 

回声确实有效,因此,安装区域设置有什么意义,例如zh_TW.UTF-8

解决方法:

What is the point of installing locale such as zh_TW.UTF-8?

区域设置规范中.[codeset]后缀的要点是指定代码集.如果对于特定语言,UTF-8是默认代码集,则不必明确指定它 – 您只需指定zh_TW(但您也可以指定zh_TW.UTF-8).如果您有可用的控制台,则可以按locale -a列出可用的区域设置.

但请注意,这可能是系统特定的！而on linux zh_TW is UTF-8 by default,on
IBM it will be BIG5
和Windows CP950！
