The following problems have been encountered with Host On-Demand running in a national language environment:
JVMs for these browsers do not currently support the display or input of User-Defined Characters; however, there are workarounds.
Internet Explorer 4.0 for Windows 98 and Windows NT has its own workaround. Use the Gaiji editor to create user-defined characters. (Click Start > Programs > Accessories to access the editor.) The workaround does not work for Windows 95. There is no way to display user-defined character on Windows 95 with Internet Explorer.
For Netscape 4 for Windows and HotJava for Windows, you must change the browsers' font-properties file to register a class for character-set conversion. For details,
refer to the files in the \ondemand\hod\samples\fonts\dbcs_udc directory after installation. This contains a sample class for character-set conversion, a
sample font-properties file, and instructions.
Host On-Demand users can remap UDC (user-defined characters) between the host and the client's personal computer (PC). The Host On-Demand server provides a UDC mapping editor. Users can use this editor to change the mapping of user defined-characters between the host and the PC. Before users start a session (3270, 5250, 3270 host print), they can edit the configuration property of this session in order to use customized UDC mapping instead default mapping.
For Host Printing support of User-Defined Characters (UDCs), you must prepare a UDC font-image file.
On a server, this file must be located in the \ondemand\hod\fonts\ directory
for access by clients. On a locally-installed client, the file must be located in the
\ondemand\lib\fonts directory.
On Windows 95, 98 or NT, you must run the w32udcnv.exe
utility to convert Windows user-defined fonts into a usable font-image file.
The utility is provided in the udc directory on the
Host On-Demand CD. It is not copied to the server or client during installation.
To use the utility:
| Platform | Font-image filename | ||
|---|---|---|---|
| Japanese Windows | jpn24.fnt | ||
| Korean Windows | kor24.fnt | ||
| Simplified Chinese Windows | chs24.fnt | ||
| Traditional Chinese Windows | cht24.fnt |
\ondemand\hod(or lib)\fonts directory.
On an OS/2 server, copy the OS/2 font-image file
$SYS1Z24.FNT to the
\ondemand\hod\fonts directory and rename it according to the table above.
On Japanese Windows 2000, a unicode version utility, w32udcnvw.exe, is provided to convert Windows user-defined fonts into a usable font-image file. If you use this utility to convert the UDCs on Windows 2000, all the UDCs defined by unicode are converted. Host On-Demand can print not only the UDCs defined in PC codes (totally 1880 characters), but also those defined in unicode including the host UDCs (0x6941-0x89BD for 930/939, 0x6941-0x7FFE for 1390/1399).
On the Windows platform, if a 3270 Display session or a 5250 Display session has been configured to use a User-3efined Character (UDC) mapping table, and that session is to be run on a Java 2-enabled browser, then in order for the UDC characters to be displayed at all the browser must be using at least the following level of Java 2 plug-in:
