Hebrew, Arabic, Thai, and Vietnamese Text

This version of Adobe Reader supports the entry and display of Hebrew, Arabic, Thai, and Vietnamese text.

Arabic and Hebrew language support

This version of Adobe Reader contains options for controlling the following aspects of the right-to-left languages Arabic and Hebrew in forms and digital signatures:

• Paragraph direction--You can select the paragraph direction to be from right to left, which properly lays out bidirectional text (right-to-left text containing numbers and text in other languages written from left to right).
• Digit style--You can select whether to use Western digits or Arabic-Indic digits when typing Arabic text.
• Ligature support--available only to Arabic text, optional ligatures will be automatically used if supported in the font.

To enable right-to-left language options in Adobe Reader:

1. Choose Edit > Preferences.

2. In the Preferences dialog box, select International Categories and select Enable Right-To-Left Language Options.

3. Click OK.

Enabling right-to-left language options displays the user interface elements for controlling paragraph direction, digit style, and ligature.

Note: The right-to-left language option is enabled by default under Arabic and Hebrew regional settings.

The following user interface elements let you control paragraph direction and digit style:

• Appearance tab of the following dialog boxes: Text Field Properties, Combo Box Properties, List Box Properties, and Button Properties, and Digital Signature Properties. In these dialog boxes, you select paragraph direction using radio buttons and you select digit style using pull-down menus. In the Radio Button Properties and Check Box Properties dialog boxes, the options to select paragraph direction and digit style are not available.
  The Appearance tab for the Digital Signatures Properties dialog box provides the digits style selection. The text direction of digital signatures is controlled by the Configure Signature Appearance dialog box available when a signature is applied to the document.
• Text Field Properties toolbar--When entering text in a Rich Text field or a Drawing Markup Text Box, you can select paragraph and font direction and digit style from the Text Properties Tool Bar.
  To change paragraph direction, use the Paragraph Direction button in the toolbar. Clicking this button displays two options: Left To Right Paragraphs and Right To Left Paragraphs, which apply to all paragraphs in the field. Paragraph alignment automatically changes according to your selection: if paragraphs are left-aligned and you change the paragraph direction to right-to-left, Adobe Reader makes all the paragraphs right-aligned, and vice versa. After changing paragraph direction, you can go back and modify the alignment of paragraphs individually.
  To change text direction of selected text and not entire paragraphs, use the Text Direction button to display a pull-down menu with three options: Automatic, Left To Right Text, and Right To Left Text. Selecting the Automatic option lays out the text depending on the paragraph's direction and the type of characters used. The Left To Right Text option lays out the text according to left-to-right rules, regardless of paragraph direction. The Right To Left Text option lays out the text according to the right-to-left rules, regardless of paragraph direction. Changing text direction is useful when the default writing direction for text in a paragraph is different for the paragraph's default writing direction or when the text direction cannot be automatically determined. For example, to make sure that phone numbers written with Western digits are displayed correctly in paragraphs of right-to-left Arabic text, select the phone numbers and choose Left To Right from the pull-down menu of the Text Direction button.
  To select the digit style of the text you type into a field, use the Arabic-Indic Digits button. This button toggles digit style from Arabic-Indic to Western and applies only to form fields with an Arabic-Indic default digit style. Using this button doesn't change the digits already in the text.
• Form Field Text Properties dialog box--In this dialog box, there are two tabs: Font and Paragraph.
  In the Font tab, you select paragraph direction using the Auto, Left To Right, and Right To Left radio buttons and you select the digit style using the Digits pull-down menus. Paragraph direction applies to the currently selected text. Digit style applies only to new digits, but not to existing digits.
  In the Paragraph tab, the paragraph direction radio buttons change the paragraph direction of all the paragraphs in the field and not just the direction of the currently selected text.
• Context menus--You can use context menus to change paragraph direction and digits.
• Configure Signature Appearance dialog box--This dialog box contains controls for specifying paragraph direction and digit style. Choosing a paragraph direction also changes the signature appearance. For example, if you set paragraph direction to Right To Left, the Name in the signature filed is placed in the right half of the field and the text is right-aligned and vice versa.

Troubleshooting Issues

If you experience problems when running Adobe Reader 7.0, this section may help you to determine the cause of those problems. For general product information and additional troubleshooting information, visit the Adobe Product Support Knowledgebase at www.adobe.com/support, or choose Online Support from the Help menu in Adobe Reader.

The Help and How To windows are not available when you open Adobe Reader from within a web browser. Solution: To access the Help button or the How To window from a task button, start Adobe Reader from outside of a web browser.

The Detect And Repair feature in Windows repairs or replaces corrupt or missing installation components.

The Enter key and the spacebar function differently in the Accessibility Setup Assistant in Windows and Mac OS. In Windows, both the Enter key and the spacebar close the wizard. In Mac OS, the Enter key advances the wizard to the next page and the spacebar closes the wizard.

Windows XP and 2000 include Microsoft Magnifier, an accessibility tool that uses the MSAA interface. When started, this tool activates accessibility in Adobe Reader until you quit Adobe Reader. Each time you open a PDF document, the following message appears, "Please wait while the document is prepared for reading." To reduce the time that Adobe Reader requires to prepare a PDF document for reading, set the Page vs. Document preference to Only Read The Currently Visible Pages in the Reading Preferences. Setting the Reading Order preference to Use Reading Order In Raw Print Stream also speeds up this process but may interfere with the functionality of Magnifier.

Use the following keyboard shortcuts to navigate between the document pane, the Help window, and the How To window:

• F6 moves focus between the document pane and the navigation pane. When focus is in the navigation pane, press the Up and Down arrow keys to cycle through the navigation tabs.
• F1 opens the Help window and moves the focus to the first item in the Help Contents tab. If the Help window is already open, pressing F1 returns the focus to the last selection. The Enter key opens the selected Help topic. Press the Up and Down arrow keys to select other Help topics.
• Alt+Tab and Alt+F6 move focus between the open Help window and the document pane. Shift+F4 also opens, and closes, the How To window. When you close the How To window, the focus moves to the document pane.

To improve the startup time and performance of Adobe Reader, defragment your hard drive by using the disk defragmenting utility before you install Adobe Reader. You can use the disk defragmenter included with your operating system or a third-party utility. Hard drives become fragmented through normal use (for example, installing and uninstalling applications, adding and deleting files). Over time, the computer is unable to locate contiguous blocks of free space and saves files in pieces across the hard drive, which increases the time required to open these files. Defragmenting the hard drive pieces files back together and improves performance.

If you scan a PDF barcode into Notepad using a handheld scanner, the resulting data may contain null bytes or illegal characters (characters that can't be typed at the keyboard). This data may execute desktop shortcuts that cause windows to open. The problem doesn't occur with all handheld scanners. No solution exists.

When you try to start Acrobat Reader in Windows 2000 after installing it on a non-system hard disk, the Acrobat installer starts and returns the message, "An installation package for the Microsoft Windows Journal Viewer cannot be found." Solution: See document 329118 in the Adobe Product Support Knowledgebase at www.adobe.com/support.

If you open a PDF file in AOL 6.0 to 9.0, the file opens in a text editor. Solution: Save the PDF file to the hard drive and open it in Adobe Reader.

GB18030: If you paste the CJK-A character U+3400 into the search field and perform a search, the search fails even if the character exists in the PDF document you're searching. The same applies to the U+3500, U+3600, and U+3700. Solution: Type the U+3400 character in the search field instead of pasting it.

If you install Adobe Acrobat Elements 6.0 after installing the full version of Adobe Reader 7.0, you may encounter an error in Acrobat Elements when you try to convert a file to PDF: "Unable to find "Adobe PDF resource file. Do you want to run installer in repair mode?" If you click Yes, the same error comes up the next time you try to convert a file to PDF in Acrobat Elements. Solution: Install Acrobat Elements 6.0 before you install Adobe Reader 7.0.5 to ensure that both applications are installed in the same folder. (Acrobat Elements 6.0 doesn't allow you to specify the install location.) Please note that Installing Adobe Reader 7.0.5 doesn't remove Adobe Reader 6.0, which is installed by Adobe Elements to the same folder. This installation of Adobe Reader 6.0 (unlike the downloaded version) doesn't interfere with Adobe Reader 7.0.5 functionality.
