Dear,

I did these:

Installed latest FUDform with chinese language
Set utf8 via 'MySQL Charset Changer'
Everything looks like fine, FUDforum's interface is Chinese and I can post or read via broswer
Then login phpMyAdmin to see whether it is ok on the MySQL side
Browse to 'fud26_forum', there are some characters which can be read by human (as attachment show) on 'name' and 'descr' column, and it should be typed Chinese characters
Used 'mysqldump' to export the database, open .sql file with text editor, as the same previously

Question:
1. What can 'MySQL Charset Changer' do? Just set exist table to specify collation? Is it possible using 'set names(utf8)' to solve this problem?
2. When I tried to modify the un-read characters to be read via phpMyAdmin, FUDforum display modified characters as '????'

(member) post Chinese characters[read] => (FUDforum) submit to MySQL=> (MySQL) store data[un-read] => (FUDforum) display Characters to visitor[read]

The changer changes the charset and the collation of the table(s), but it cannot change the existing data within those tables.

Thanks for your replay, Ilia.

I'm a newbie, looks like there are still un-read Chinese characters after set utf8 via 'MySQL Charset Changer'. I searched on Internet, there are some usefulness topic, like http://ilia.ws/archives/103-mysql_real_escape_string-versus-Prepared-Statem ents.html.

So I tried to change some(add SET NAMES 'UTF8'):

fudforum/index.php

from:

if (!defined('fud_sql_lnk')) {
	$connect_func = $GLOBALS['FUD_OPT_1'] & 256 ? 'mysql_pconnect' : 'mysql_connect';
	$conn = $connect_func($GLOBALS['DBHOST'], $GLOBALS['DBHOST_USER'], $GLOBALS['DBHOST_PASSWORD']) or die (fud_sql_error_handler("Initiating $connect_func", mysql_error(fud_sql_lnk), mysql_errno(fud_sql_lnk), "Unknown"));
	define('fud_sql_lnk', $conn);

to:

if (!defined('fud_sql_lnk')) {
	$connect_func = $GLOBALS['FUD_OPT_1'] & 256 ? 'mysql_pconnect' : 'mysql_connect';
	$conn = $connect_func($GLOBALS['DBHOST'], $GLOBALS['DBHOST_USER'], $GLOBALS['DBHOST_PASSWORD']) or die (fud_sql_error_handler("Initiating $connect_func", mysql_error(fud_sql_lnk), mysql_errno(fud_sql_lnk), "Unknown"));
        mysql_query("SET NAMES 'UTF8'");
	define('fud_sql_lnk', $conn);

And then, looks like it can safe Chinese characters at MySQL(v4.1+). But there is a still ????? at fudforum/adm/admforum.php, but fudforum/adm/admcat.php is ok.

are the characters pertain to new information into the forum or the old one?

You may want to modify admpanel.php inside adm/ dir to send UTF-8 charset rather then the default ISO-8859-15

Thanks for your reply, Ilia.

1. It is exist (forum) information display as ????? (manual add before via phpMyAdmin as utf8 encode)on adm/admforum.php

2. It is already set 'charset=utf-8' at admpanel.php
source of /adm/admpanel.php

<head>
<link rel="StyleSheet" href="adm.css" type="text/css">
<meta http-equiv="Content-Type" content="text/html; charset=<?php 
if (file_exists($DATA_DIR.'thm/'.$usr->theme_name.'/i18n/'.$usr->lang.'/charset')) {
	echo trim(file_get_contents($DATA_DIR.'thm/'.$usr->theme_name.'/i18n/'.$usr->lang.'/charset'));
} else if (file_exists($DATA_DIR.'thm/default/i18n/'.$usr->lang.'/charset')) {
	echo trim(file_get_contents($DATA_DIR.'thm/default/i18n/'.$usr->lang.'/charset'));
} else {
	echo 'us-ascii';
}
?>">
</head>

Output of /adm/admforum.php

<head>
<link rel="StyleSheet" href="adm.css" type="text/css">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>

Is the info displayed as ???? new or old, meaning was it added before or after charset change?

Have you tried changing the charset in the browser to BIG-5?

Thanks for your replay, Ilia.

I did these:

utf8 charset: Category name is fine, but forum name(and description) not.

big5 charset: Category name isn't fine, and forum name(and description) too.

gb2312 charset: Category name isn't fine, and forum name(and description) too.

gbk charset: Category name isn't fine, and forum name(and description) too.

Have you tried re-typing the name while in utf8 mode?
