把mysql 4.0.20的数据表文件(myisam)格式迁移到mysql 5.0下面后phpmyadmin出现乱码

把mysql 4.0.20的数据表文件(myisam)格式迁移到mysql 5.0下面后phpmyadmin出现乱码

如何处理？

共设置了两个地方：

修改: ./libraries/dbi/mysql.dbi.lib.php
修改函数:

function PMA_DBI_connect($user, $password, $is_controluser = FALSE) 
 注释掉其中的这一行:
PMA_DBI_postConnect($link, $is_controluser);

修改:./libraries/config.default.php
把下面3行修改其值为"gb2312"

/**
 * Default language to use, if not browser-defined or user-defined
 *
 * @global string $cfg['DefaultLang']
 */
//$cfg['DefaultLang'] = 'en-iso-8859-1';
$cfg['DefaultLang'] = 'gb2312';

/**
 * Force: always use this language - must be defined in
 *        libraries/select_lang.lib.php
 * $cfg['Lang'] = 'en-iso-8859-1';
 *
 * Regular expression to limit listed languages, e.g. '^(cs|en)' for Czech and
 * English only
 *
 * @global string $cfg['FilterLanguages']
 */
 //$cfg['FilterLanguages'] = '';
$cfg['FilterLanguages'] = 'gb2312';

/**
 * Default character set to use for recoding of MySQL queries, does not take
 * any effect when character sets recoding is switched off by
 * $cfg['AllowAnywhereRecoding'] or in language file
 * (see $cfg['AvailableCharsets'] to possible choices, you can add your own)
 *
 * @global string $cfg['DefaultCharset']
 */
//$cfg['DefaultCharset'] = 'iso-8859-1';
$cfg['DefaultCharset'] = 'gb2312';
