Bidirectional considerations

The following sections describe specific issues that you might encounter when working with bidirectional text. To work with bidirectional text, you must enable bidirectional support.

Visual mode display in the Source page

When working in the Source page editor environment, you can use the Shift+NumLock key combination to enable or disable the Visual display format for bidirectional data.

Visual mode text entry in the Source page

In Windows®, you can directly enter English data in the Source page editor. However, if you are in Visual mode, you cannot directly type Arabic or Hebrew data in the Source page editor.

To enter or edit bidirectional data when in Visual mode, use the Ctrl+NumLock key combination to invoke a pop-up Source page editor. This editor enables Visual ordering of text and Visual input key functions.

If you have selected text in the Source page when you invoke the editor, it will be displayed as initial data in the pop-up dialog. If no text is selected, the editor will not display any initial data.

The data from the Visual editor dialog is saved in Visual format and placed at the cursor position in the Source page. If text is selected in the Source page, it will be overwritten with the input from the Visual editor.

While in Visual mode in the Linux® environment, you cannot directly enter data in the Source page editor. You must use the pop-up editor to enter or edit text in the Source page. Use the Ctrl+NumLock key combination to invoke the dialog.

Error tracing

If general logging is enabled, you can trace bidirectional function errors by checking the log files.
The bidirectional functions that are logged are as follows:
  • Screen Reverse
  • Numerical Swapping
  • Symmetrical Swapping
  • Push and Autopush
  • Switching between Hindi and Arabic numerals
  • Field Reverse
  • Switching between Visual and Logical modes

Linux considerations

The Home and End functions are not fully implemented for the SuSE Linux 9.2 platform, and might not function as expected. The functions work as designed on the Red Hat Enterprise Linux 3.1 platform.

Arabic considerations

For Arabic content, the following Seen tail character limitations exist:
