When you create an application with bidirectional support, follow the guidelines in this table.
| Complies | Not applicable | Rule |
|---|---|---|
| Software design must allow for bidirectional data to be passed to applications in the same order that a speaker of the language can spell it out. | ||
| The product design must allow for the implementation of the correct handling of bidirectional keyboard and presentation functions. | ||
| Designing of a function that implies logical movement of cursor or characters must permit mirroring of that function. | ||
| Keys or operations labeled with directional icons or symbols must perform according to the icon or symbol. | ||
| Keyboard nomenclature for mirrored functions must be independent of the direction of data or text entry. | ||
| Display functions must not assume a left-to-right orientation. | ||
| Field attributes must contain room for directional information. | ||
| Indicator location must be reserved for the current direction of the cursor (direction of input). | ||
| The design must allow for independent handling of graphic and text orientation. | ||
| Provision must be made to allow shape determination to be performed. | ||
| The deshaping must be definable. | ||
| Provision must be made to allow the selection of the appropriate presentation shape for the numerals. | ||
| Characters must be allowed to touch each other on printers and displays. | ||
| Indicator locations should be reserved for screen and field orientation, current level of nesting, status of push (nesting mechanism), and status of symmetric swapping. | ||
| The design should provide for a method to indicate to the user the nesting structure of a string. | ||
| A system-wide method of deshaping Arabic characters or character strings should be provided. | ||
| An indicator location should be provided for the status of shape determination. | ||
| A method should be provided so that proportional spacing can be provided. | ||
| A method should be provided to allow alignment of the baseline of Arabic and Latin characters (including Hindi and Arabic shapes for numerals). |
