GB18030 is a character-encoding standard defined by the government of the People's Republic of China (PRC) that encompasses all the characters in the languages of the nationalities included in the PRC. A product released after GB18030 was promulgated must conform to this standard in order to be sold in the PRC.
Characters in GB18030 are encoded in either 1 byte, 2 bytes, or 4 bytes.
Windows 2000, Windows XP, and Internet Explorer 6.0 support GB18030, but earlier Windows platforms and Internet Explorer 5.5 do not.
Contact Nicrosoft to determine whether you need to download and install the Microsoft GB18030 support package.

The following problems have been encountered with Host On-Demand running in a Chinese (Simplified) language environment:
When the Host On-Demand client is run on the Linux platform with a Java 2-enabled browser and with IBM Java 2 version 1.3.1 Service Release 1 (SR1) or earlier, and with GB18030 support installed, 4-byte GB18030 characters may be displayed incorrectly or may not be displayed at all in 3270 and 5250 display sessions.
The fix is to upgrade IBM Java 2 to version 1.3.1 Service Release 2 (SR2).
When the Host On-Demand client is run on the AIX platform with a Java 1 browser, the user cannot enter Chinese (Simplified) characters in a 3270 or 5250 session.
The workaround is to use a Java 2-enabled browser and a supported version of Java 2.
On a Windows client with a Java 2 browser, and with the client using the Simplified Chinese locale and the Microsoft GB18030 support package, some 4-byte GB18030 characters are not displayed correctly in 3270 and 5250 display sessions.
The characters may be displayed as square blocks or may not be displayed at all.
For wrongly displayed characters from languages other than Arabic, no fix exists, because the characters have not yet been added to the Unicode standard.
For wrongly displayed characters from the Arabic language, the fix is as follows:

On a Windows 2000 client with a Java 2 browser, and with the client using the Simplified Chinese locale and the Microsoft GB18030 support package, some GB18030 characters are not displayed correctly on the Host On-Demand desktop.
The characters may be displayed as square blocks or may not be displayed at all.
This problem may also affect session menus, message boxes, help, and other Host On-Demand text.
This problem may occur whether or not IBM WorldType font Monotype Sans Duospace WT SC is installed.
The cause or causes of this problem may be either or both of the following:
The fix is as follows:
On the Simplified Chinese OS/2 platform, the JVM is not able to control the OS/2 IME if the English IME is selected as the default system IME. This causes Host On-Demand to fail to switch between SBCS/DBCS IME modes when the Auto IME option is turned on.
To work around the problem and change the default IME, download a utility called setime.cmd from the IBM Host On-Demand service key site and run it. The service key site is located at http://www6.software.ibm.com/aim/home.html. You will need to register on this site if you have not already done so.
Take these steps to use the setime.cmd utility:
On Chinese (Simplified) Windows 95 and NT with Netscape 4.06, you may not be able to type the correct Chinese characters when using the Input Method Editor (the IME lets you input double-byte characters in addition to alphanumeric characters). You might be able to solve this problem by installing the latest version of Netscape 4.06.
Netscape 4.x for Linux does not support GB18030. Therefore Host On-Demand cannot display GB18030 characters correctly on Linux with Netscape 4.x. If you are experiencing this problem, upgrade to Netscape 6.0.
With Host On-Demand in PDT mode, and using the Epson LQ1600KIII+ printer, you can print only the Chinese character set (27484 characters) from GB18030. You cannot print GB18030 non-Chinese characters (20417 characters).
To print these characters, use Host On-Demand GDI Printing mode instead of PDT mode.
Characters that cannot be printed include:
