gettext设置无法正常工作

Question

I had gettext working, but now it suddenly won't translate. I get find out whats going on. I am trying to use /sys/locale/no_NO/LC_MESSAGES/messages.po to translate the page to norwegian.

/public/home.php

$locale = "en_US";
if (isSet($_COOKIE['lang'])) $locale = $_COOKIE['lang'];
putenv("LC_ALL=$locale");
setlocale(LC_ALL, $locale);
bindtextdomain("messages", "../sys/locale");
textdomain("messages");

echo "<p>locale: " . $locale . " "; 
echo gettext("Home"); 
exit(); 

This prints out

locale: no_No Home when I should be locale: no_No Hjem

Answer 1

With Japanese I have to do the following:

putenv("LANG=ja_JP.UTF-8");
setlocale(LC_MESSAGES, 'ja_JP.UTF-8');
bindtextdomain('messages', '../locale');
bind_textdomain_codeset('messages', 'UTF-8');
textdomain('messages');

With other languages I find I do not always have to add the encoding suffix, it is very inconsistent. Similarly I cannot just use "ja" when "en" works fine.

setlocale returns false unless the locale is listed in /usr/share/i18n/SUPPORTED but translations will often work despite the error.
