Supporting China National Standard – GB 18030-2005:

This document provides additional information for the product’s Readme file with regard to GB18030-2005 support in Acrobat product features.

What’s new and improvement in terms of supporting China National Standard GB 18030-2005:

· Acrobat could not be installed in the directory which contains GB18030 4-byte characters in the previous release. This issue has been fixed in this new release (#2647649 fixed).

· PPPPortfolio function in Acrobat X is based on Flash Player 10.x. It has better supported for input, display and edit GB18030 4-byte characters in PDF Portfolio in this release (#1750974 & #1763303 fixed).

· In the previous release a problem was reported when creating PDF from the plain text file which has a mixed of 2 & 4 byte characters in the file name. This issue has been fixed in this new release (#2580994 fixed).

· PDFMaker for Macintosh is not included in this release.

Limitation

· Acrobat is software that can be installed and runs on Windows. Limitation of supporting GB 18030 standard platforms will limit the functionality of the product.

· MS “Notepad” on Windows does not support 4-byte GB 18030 encoding characters. It is suggested that PDF should not be created from a raw text file with 4-byte GB 18030 characters via Notepad.

· Acrobat handles all text as Unicode (supports surrogates too) and the application uses system APIs for displaying the text in the UI. If there is any specific problem with text rendering, it may be an operating system limitation.

Known Issues

· Paper Capture provides OCR recognition for most GB2312 characters (over 4200 characters). These GB18030 characters in the Form Location characters are specified by an OCR engine which is supplied by a third-party company.

· If PDF document is created from a .PS file using Acrobat Distiller, the Title property of the PDF is inherited from the original file which generated the .PS file. The GB18030 4-byte characters in the Title field will display as “?” in the Description page of Document Properties Dialog (#2654552).

· As a Form distributer, user can view tracker detail either within Tracker or from the PDF created from Tracker details. Some of the GB 18030 4-byte characters can not be displayed in Form Location of the PDF created from Tracker details (#2715473).

The workaround is to viewing the Form Location information within Tracker since the GB18030 characters can be displayed correctly here.
