Bidirectional text is text containing both right-to-left and left-to-right directional runs. Bidirectional text support is available on all platforms, in the user interface and in all exported documents:
Export to HTML
Office HTML
Export to PDF.
Bidirectional text is rendered equally in all possible output modes, but with the following restrictions:
Ligatures are not placed between Arabic letters if the text is exported to a PDF file. A ligature is a sequence of characters displayed as a single unit replacing characters that occur next to each other when common components are shared.
In Office HTML Export, the bidirectional processing is performed by Microsoft Excel after the exported document is opened. Due to this behavior, text rendering may differ from what is presented in the Designer or Hyperion System 9 BI + Workspace.
Release 8.5 does not change the system-defined bidirectional behavior of the following user interface controls: edit, drop-down, and list-box. This is true both for clients (studio and web client) and the Hyperion System 9 BI + Workspace.
