If you are using a Unicode system, you can use Windows Wordprocessor Integration (WWI) in ASCII or Unicode mode. For the same SAP system, it is not possible to run some of the WWI generation servers with ASCII and others with Unicode, in order to generate some reports with ASCII and some with Unicode depending on a condition, for example.

If you are using a Unicode system with WWI in ASCII mode, the system converts the data that needs to be inserted in a report to the respective ASCII code page. This can lead to problems in the following cases:

• In languages that contain characters that are not in any standardized ASCII code page and therefore do not exist in any ASCII fonts

• In data values for which WWI has no language or code page information, such as for parameter symbols

If you are using WWI in Unicode mode, the system inserts the data into reports in Unicode format. This has the following disadvantages:

• The file size of reports may increase.

• The choice of Unicode fonts is more limited than that of ASCII fonts.

• Using a Unicode font can distort the familiar script. For example, the appearance of the common Unicode font Arial Unicode MS is not the same as Arial.

• Versions of Microsoft Word that are older than Microsoft Word 2000, for example, Microsoft Word 97, are not supported.

The IMG section Windows Wordprocessor Integration (WWI) describes how you set up WWI in ASCII mode. This IMG activity describes what you need to observe in addition if you want to use WWI in Unicode mode.

If you want to use WWI in Unicode mode, make the following settings:

• In the IMG activity Specify Environment Parameters, set the environment parameter WWI_IS_UNICODE to X.

• In the procedure described in the IMG activity Set Up RFC Destination, on the MDMP & Unicode tab page, select the Unicode radio button.

• Start the WWI generation server with the programs WWIRFCSVU.EXE (for console application) or WWISVCU.EXE (for the Windows service) instead of WWIRFCSV.EXE or WWISVC.EXE (see Set Up Generation Server As a Console Program and Set Up Generation Server As a Windows Service).

For a console application, you enter the following additional line in the configuration file SAPRFC.INI for each destination:

PROGRAM=wwirfcsvU.exe

• In the configuration file WWI.INI on the generation server and on the WWI front-end installations, add a line with font information for Unicode, for example:

[Fonts]
1160=Times New Roman,Arial,Courier New,Helvetica
...
4102=Arial Unicode MS

In this example, the fonts Times New Roman, Arial, Courier New, and Helvetica would be replaced by Arial Unicode MS. Under 4102, enter only fonts that are based on Unicode.

• Install the necessary Microsoft Word components for multilingual support.
