今天更新了一下ThinkPad ACPI电源管理驱动(Windows 7/Vista/XP)和集成System Interface的Hotkey驱动程序(Windows 7/Vista/XP 32-bit,64-bit/2000) 驱动后，重启电脑，提示信息又回来了～

SquirrelMail attempts to set the language in many ways. If it
can not figure it out in another way, it will default to this
language. Please use the code for the desired language.

Happy SquirrelMailing!

cd /var/www/html/squirrelmail/config
./conf.pl
选择10 设置语言为zh_CN
默认字符集为gb2312
保存退出，重新刷新webmail页面，就成中文了
但是登录进入后，左边的Drafts，sent，trash还是英文
修改/var/www/html/squirrelmail/local/zh_CN/LC_MESSAGES/squirrelmail.po，
增加msgid和msgstr,
修改完毕后，用 msgfmt -o squirrelmail.mo squirrelmail.po 来格式化一下。

找到第4283行，红色部分为新增代码，修改如下：

}elseif(strlen($field_val) > $listview_max_textlength) {
 if($default_charset == 'UTF-8'){
 $temp_val = mb_substr($field_val, 0, $listview_max_textlength, $default_charset).'...';
 }else{
 $temp_val = substr(preg_replace("/(<\/?)(\w+)([^>]*>)/i","",$field_val),0,$listview_max_textlength).'...';
 }
 }
 } else {

注意：请确保php开启了mb_substr函数支持。

在php.ini中找到“;extension=php_mbstring.dll”去掉前面的分号“;”，然后重启服务即可

导入数据文件CSV中文乱码修正

在Smarty/templates/ImportStep1.tpl中的第99行插入<option value=”GBK”>GBK</option>

<select name="format" class="small">
<!-- value must be a known format for mb_convert_encoding() -->
 <option value="GBK">GBK</option> // <<插入一行
 <option value="ISO-8859-1">ISO-8859-1</option>
 <option value="UTF-8">UTF-8</option>
</select>

导出数据文件CSV中文乱码修正

修改include/utils/export.php中的第208，232和240行

/** Output header information */
 echo iconv("UTF-8", "GBK", $header); //原来: echo $header;

/** Output each row information */
 echo iconv("UTF-8", "gbk", $line); //原来: echo $line;
 }
 $log->debug("Exiting export method ...");
 return true;
}

/** Send the output header and invoke function for contents output */
header("Content-Disposition:attachment;filename={$_REQUEST['module']}.csv");
header("Content-Type:text/csv;charset=gbk"); //原来: header("Content-Type:text/csv;charset=UTF-8");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT" );
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );
header("Cache-Control: post-check=0, pre-check=0", false );

下载Simsun解压后，将Simsun.ttf文件复制到修改\Image\Canvas\Fonts\目录下
修改\Image\Canvas\Fonts\fontmap.txt，最后增加一行：
Simsun, Simsun.ttf

修改\include\utils\GraphUtils.php，在第22行插入以下代码：
DEFINE("FF_DROIDSANSFALLBACK",'Droid Sans Fallback');
将第43行的 case 'cn_zh': 修改为 case 'zh_cn':

保存即可。

1，修改 当前表插入字段
2，vtiger_field 增加记录
3，vtiger_def_org_field 增加记录 INSERT INTO `supportcrm`.`vtiger_def_org_field` (`tabid`, `fieldid`,`visible`, `readonly`) VALUES ('32', '621', '0', '1');
4，vtiger_fieldmodulerel 增加记录 INSERT INTO `supportcrm`.`vtiger_fieldmodulerel` (`fieldid`, `module`,`relmodule`, `status`, `sequence`) VALUES ('621', 'ServiceContracts', 'SalesOrder', '', '0');
5，vtiger_profile2field 增加记录（增加多条记录） INSERT INTO `supportcrm`.`vtiger_profile2field`(`profileid`, `tabid`, `fieldid`, `visible`, `readonly`) VALUES ('4', '32', '621', '0', '1');

此方面修改会导致以下问题：

1.通过系统新增自定义字段时，会导致id号重复，导致首次添加的自定义字段无效，再次添加一些即可，暂未发现使用异常（可以尝试第一步修改为通过自定义字段添加字段）

2.修改之前添加的服务合同记录无法修改保存，需要重新添加。

PDF修正方法:

对./vtlib/Vtiger/PDF/TCPDF.php文件修改,即:在第75和76行插入 $family = ‘stsongstdlight’;

if ($size == 0) {
 $size = $this->FontSizePt;
 }
$family = 'stsongstdlight'; //<插入的语句
// try to add font (if not already added)
$fontdata = $this->AddFont($family, $style);
$this->FontFamily = $fontdata['family'];

对.include/tcpdf/TCPDF.php文件修改,即:在第3066和3067行插入 $family = ‘stsongstdlight’;

if ($size == 0) {
 $size = $this->FontSizePt;
 }
$family = 'stsongstdlight'; //<插入的语句
 // try to add font (if not already added)
$fontdata = $this->AddFont($family, $style);
$this->FontFamily = $fontdata['family'];
