Since mid 2003, Mr. Jia Ming Deng (nickname Firefly, now listed on JCA), a Chinese Linux hacker from Taiwan, has been working on a set of OpenOffice.org patches that has significantly enhanced the font naming, selection and screen appearance for many CJK OOo Linux users. His initial patches for 1.x are considered either too large and too risky to merge to the mainline OOo code base, and hence was only provided as a third party download listed in the [http://zh.openoffice.org/addons.html Add-On section] of [http://zh.openoffice.org/ Chinese (zh) OpenOffice.org Page].

Introduction

Since mid 2003, Mr. Jia Ming Deng (nickname Firefly, now listed on JCA), a Chinese Linux hacker from Taiwan, has been working on a set of OpenOffice.org patches that has significantly enhanced the font naming, selection and screen appearance for many CJK OOo Linux users. His initial patches for OOo 1.x were either considered too large or too risky to merge into the mainline OOo code base, and hence were only provided in the form of a modified third-party build listed in the Add-On section of Chinese (zh) OpenOffice.org Page.

With the release of OpenOffice.org 2.x, however, some of the greater obstacles, such as fakestyle printing for regular-only font (for instance, AR PL Mingti2 Big5 under Linux) has already started to work; whereas the screen appearance of fakestyle (or fakebold according to OOo bug database) is still nowhere to be seen in the Linux version.

This time around, however, with Firefly's JCA status already cleared and that his patches are now divided into smaller groups for easier review, the path is finally cleared for bringing most of his contributions into the mainline OpenOffice.org codebase. This should benefit thousands of CJK OpenOffice.org users out there. Some of his patches solved bugs or missing features in Linux version, while other patches would benefit users on all platforms.

以下簡述何謂「自動尋字」及「字體自動匹配」：


　　OpenOffice.org 是一套功能十分強大的辦公室軟體，但對非英語系的使用者而言，最大的弱點，就是無法解決兩個不同使用者之間，字體不一致的問題，舉例來說，某甲所製作的文件，用了 A 字型公司的字體，但某乙卻沒有 A 公司的字體，當某乙用OpenOffice 開啟某甲的文件時，會有兩種可能的情況：一、看不到這些 A公司的字，結果可能是空白，可能是方框□□□。二、看得到這些字，但卻亂找字體來顯示，卻無法完全顯示，或是字體間距不對，造成疊在一起的情況，一般解決方式，就是設定替代字型，但是，字型何其多，每個人多少都不一樣，解決字體相異的問題，不該丟給使用者自行解決，無論如何，這都不是我們要的結果。
　　以上情形，中文加強版的解決方式是加上「自動尋字」及「字體自動匹配」，自動尋字，顧名思義就是當指定的字體中，沒有該字時，會自動啟動尋字功能，找出系統中，有該字的字體，加以顯示，而自動尋字也並非盲目找字，它會依據文件指定的字體性質，作「字體自動匹配」，所以「自動尋字」及「字體自動匹配」兩個功能，是有緊密關聯的；但，甚麼又是「字體自動匹配」呢？
　　簡單地說，「字體自動匹配」就是依據指定字體的性質，譬如某甲用了A公司的黑體，但某乙沒有A公司的黑體，卻有B公司的黑體，如果依照OpenOffice原始的方式，會出現空白字或是用楷體來替代，而中文加強版「字體自動匹配」卻可以分辨出『黑體』性質，而以B公司的黑體來顯示A公司的黑體文件，盡量做到文件字體的一致性，同時也解決的排版不一致的問題，包括輸出到PDF檔案或印表機亦同。
　　中文加強版的解決方式，不敢說是完美無暇，但相當程度解決了非英文使用者的問題，相信中文加強版提出的方式，連微軟的 Office 都沒有這樣的能力。
