[Old System] CentOS 5.x + PHP 5.3 + SquirrelMail Config Charset to TIS-620

$config_version = '1.4.0';

$lossy_encoding = false;
Tested send/receive The Email with Thai language Subject + Body + Reply to work normally both Hotmail and Gmail.


[New system] CentOS 7.x + PHP 5.5 + SquirrelMail

If I config $default_charset = 'ISO-8859-1';
tested received / sent The Email with Thai language will not work both Hotmaill and Gmail can read subject and body but unable encoding to Thai language.

If I config $default_charset = 'utf-8';
tested received / sent The Email with Thai language will work with Gmail but have a problem with Hotmail unreadable to read thai font.

If I config $default_charset = 'tis-620';
tested received / sent The Email with Thai language will work with Hotmaill but have a problem with Gmail unreadable to read thai font.

Hello,

I have no idea on how to fix it, probably someone has.

Do you have such an issue with Roundcube?
