Unicode support for i5/OS and OS/400 using Coded Character Set Identifiers

General information

In a 5250 Display session, Host On-Demand supports the display of Unicode data located in fields tagged with Coded Character Set Identifiers (CCSIDs). The Enable Unicode Data Stream option in the 5250 Display session configuration window must be set to Yes (see ENPTUI).

Host On-Demand does not support this feature in a 5250 Printer session.

Host On-Demand supports the following CCSIDs:

• 13488 (hexadecimal 0x34B0)
• 17584 (hexadecimal 0x44B0)

Host requirements

The iSeries host must be running one of the following levels of i5/OS or OS/400:

• OS/400 V5R2 with an appropriate manufacturing refresh (see the readme file for details).
• i5/OS or OS/400 V5R3 or higher.

Client workstation requirements

The following requirements apply to the client workstation:

• Java 1 or Java 2
  For bidirectional languages the client workstation must use one of the following:
  • A Java 2-enabled browser with the Host On-Demand client
  • Web Start Host On-Demand client
  For all other supported languages the Host On-Demand client can use any one of the following:
  • A Java 1 browser with the Host On-Demand client
  • A Java 2-enabled browser with the Host On-Demand client
  • Web Start Host On-Demand client
• Fonts
  
  • Bidi languages
    Use the Courier New font that is already installed on the client workstation. For more information see Understanding bidirectional language support (Arabic and Hebrew).
  • Other languages
    The client workstation must be configured to use one of the Monotype Sans Duospace WT fonts. These fonts are IBM WorldType fonts. See Configuring the font on the client.

Limitations

This feature has the following limitations:

• An SBCS session supports only single-width Unicode characters.
• A DBCS session supports both single-width Unicode characters and double-width Unicode characters.
• However, a DBCS session supports only those double-width Unicode characters that occur in the Monotype Sans Duospace WT font file corresponding to the code page that the session is using. For example, a 5250 Display session configured with Japanese code page 930 supports only those double-width Unicode characters that occur in the Monotype Sans Duospace WT J font file (mtsansdj.ttf).
• This feature does not support the Hindi and Thai code pages.
• This feature does not imply support for GB18030 Phase 2.
• This feature does not support any combining characters in CCSID-based entry field and output data.
• This feature does not support Language Tags (Plane 14) of UTF-16, because Host On-Demand does not support multiple fonts within one session.
• This feature does not support Tamil and Teluga Unicode characters.
• This feature does not support Tibetan and Mongolian Unicode characters.
• This feature does not support surrogate Unicode characters. These characters are accepted but are displayed incorrectly by Java.

Configuring the font on the client

Obtaining the font file

The client workstation must be configured to use one of the IBM WorldType Monotype Sans Duospace WT fonts. The following table shows which font name and font file should be used for each language:

The next subsections describe how to configure the client workstation to use the font.

If you are using a Java 2-enabled browser and the IBM Java 2 plug-in

If you are using a Java 2-enabled browser (such as Netscape 6.0 or Internet Explorer with a Java 2 plug-in) and the IBM Java 2 plug-in, follow the steps in this section to configure the font on the client.

1. These instructions use the SBCS languages as an example, but the instructions are similar for Japanese, Korean, Simplified Chinese, and Traditional Chinese. However, remember to use the correct Monotype Sans Duospace WT font name and font file for your language, as described in Obtaining the font.

2. In the IBM Java 2 directory, find the font.properties file corresponding to your language:

   • For SBCS languages, use font.properties
   • For Japanese, use font.properties.ja
   • For Korean, use font.properties.ko
   • For Simplified Chinese, use font.properties.zh
   • For Traditional Chinese, use font.properties.zh_TW
   For example, assuming that IBM Java 2 has been installed in the c:\Program Files\IBM\Java14 directory, the fully qualified file name for the font.properties file for the SBCS languages is c:\Program Files\IBM\Java14\jre\lib\font.properties.



3. Modify the font.properties file corresponding to your language as follows:

   1. Open the file with an ASCII editor.

   2. Find the line beginning with the following characters:
      monospaced.0=

   3. Modify the group of lines as follows:

      • Move the Monotype Sans Duospace WT line to the top.
      • Renumber the lines.
      For example, for the SBCS languages, modify these lines in the font.properties file:
      
      monospaced.0=Courier New
monospaced.1=Lucida Sans Typewriter Regular
monospaced.2=Lucida Sans Regular
monospaced.3=Monotype Sans Duospace WT J

      These lines should read as follows:
      
      monospaced.0=Monotype Sans Duospace WT J
monospaced.1=Courier New
monospaced.2=Lucida Sans Typewriter Regular
monospaced.3=Lucida Sans Regular


   4. Make the same changes for the group beginning with monospaced.italic.0.

   5. Make the same changes for the group beginning with monospaced.bold.0.

   6. Make the same changes for the group beginning with monospaced.bold.italic.0.

   7. Close the file.

4. Restart the browser.

If you are using a Java 2-enabled browser and the Sun Java 2 plug-in

If you are using a Java 2-enabled browser (such as Netscape 6.0 or Internet Explorer with a Java 2 plug-in) and the Sun Java 2 plug-in, follow the steps in this section to configure the font on the client.

1. These instructions use the SBCS languages as an example, but the instructions are similar for Japanese, Korean, Simplified Chinese, and Traditional Chinese. However, remember to use the correct Monotype Sans Duospace WT font name and font file for your language, as described in Obtaining the font.

2. In the Sun Java 2 directory, find the font.properties file corresponding to your language:

   • For SBCS languages, use font.properties
   • For Japanese, use font.properties.ja
   • For Korean, use font.properties.ko
   • For Simplified Chinese, use font.properties.zh
   • For Traditional Chinese, use font.properties.zh_TW
   For example, assuming that Sun Java 2 has been installed in the c:\Program Files\Java\j2re1.4.1_02 directory, the fully qualified file name for the font.properties file for the SBCS languages is c:\Program Files\Java\j2re1.4.1_02\lib\font.properties.



3. Modify the font.properties file corresponding to your language as follows:

   1. Open the file with an ASCII editor.

   2. Find the line beginning with the following characters:
      monospaced.0=

   3. Modify the group of lines as follows:

      • Add a line at the top for the Monotype Sans Duospace WT font corresponding to the font.properties file. Remember to use the correct Monotype Sans Duospace WT font name for your language, as described in Obtaining the font.
      • Renumber the lines.
      For example, for the SBCS languages, modify these lines in the font.properties file:
      
      monospaced.0=Courier New,ANSI_CHARSET
monospaced.1=WingDings,SYMBOL_CHARSET
monospaced.2=Symbol,SYMBOL_CHARSET

      The lines should read as follows:
      
      monospaced.0=Monotype Sans Duospace WT J
monospaced.1=Courier New,ANSI_CHARSET
monospaced.2=WingDings,SYMBOL_CHARSET
monospaced.3=Symbol,SYMBOL_CHARSET


   4. Make the same changes for the group beginning with monospaced.italic.0.

   5. Make the same changes for the group beginning with monospaced.bold.0.

   6. Make the same changes for the group beginning with monospaced.bold.italic.0.

   7. Find the lines that begin with filename.
      
      
   8. Add the following line anywhere in the list, for example, before the first line that begins with filename.:
      
      • If your language is any SBCS language, add the following (the same as for Japanese): filename.Monotype_Sans_Duospace_WT_J=mtsansdj.ttf.
        
        
      • If your language is Japanese, add filename.Monotype_Sans_Duospace_WT_J=mtsansdj.ttf.
        
        
      • If your language is Korean, add filename.Monotype_Sans_Duospace_WT_K=mtsansdk.ttf.
        
        
      • If your language is Simplified Chinese, add filename.Monotype_Sans_Duospace_WT_S=mtsansds.ttf.
        
        
      • If your language is Traditional Chinese, add filename.Monotype_Sans_Duospace_WT_T=mtsansdt.ttf.
        
        
   9. Find the line that begins with exclusion.monospaced.0=.
      
      
   10. Comment out this line by typing a # as the first character of the line, for example, #exclusion.monospaced.0=0100-20ab,20ad-f8ff.
       
       

   11. Close the file.

4. Restart the browser.

If you are using Netscape 4.x

If you are using Netscape 4.x, then follow the steps in this section to configure the font on the client.

1. These instructions use the SBCS languages as an example, but the instructions are similar for Japanese, Korean, Simplified Chinese, and Traditional Chinese. However, remember to use the correct Monotype Sans Duospace WT font name and font file for your language, as described in Obtaining the font.

2. In the Netscape directory, find the font.properties file corresponding to your language:

   • For SBCS languages, use font.properties.
   • For Japanese, use font.properties.ja.
   • For Korean, use font.properties.ko.
   • For Simplified Chinese, use font.properties.zh.
   • For Traditional Chinese, use font.properties.zh_TW.
   For example, assuming that Netscape 4.x has been installed in the c:\Program Files\Netscape\Communicator directory, the fully qualified file name for the font.properties file for the SBCS languages is c:\Program Files\Netcape\Communicator\Program\java\classes\font.properties.



3. Modify the font.properties file corresponding to your language as follows:

   1. Open the file with an ASCII editor.

   2. Find the line beginning with monospaced.0=.

   3. Modify the group of lines as follows:

      • Add a line at the top for the Monotype Sans Duospace WT font corresponding to the font.properties file. Remember to use the correct Monotype Sans Duospace WT font name for your language, as described in Obtaining the font.
      • Renumber the lines.
