Description fundawang 2006-03-26 08:11:43 UTC 
There are a lot of font vendors in China, and they are providing same fonts in 
different names. For instance, Vender Foo named its Song as "Foo Song", vender 
Bar named as "Bar Song". But acturally, Foo Song and Bar Song renders 90% the 
same as each other.

Considering the huge number of styles of Chinese fonts, I would suggest some 
smart substitution algorithm on this issue. Patch made by Firefly follows.

Good idea, thanks. But can someone please translate the comments in this patch
from Chinese to English please?

The overall algorithm is:
1. Guess the font family group based on the last few chraracters of family name.
2. If the font family group of the font document is using and the font 
installed in system are the same, then the two fonts are considered as fungible.
3. The document will be displayed and printed in the first fungible font.

unfortunately, this task won't make it for OOo 2.0.4 due to some resource
constraints. Retargeting to OOo 2.x

I test this patch.
After patch, "scalc-format-cell dlg" appears very slowly :-(
Comment 9 Mathias_Bauer 2006-12-21 08:54:53 UTC 
wrong component
Comment 10 hdu@apache.org 2007-04-17 14:46:43 UTC 
The idea for the better replacement is very good, but the patch's chinese
comments for generic code, the performance hit caused by the patch and the very
many side effects it introduces for other script types makes it impossible to
apply the patch directly. Changing the issue status to "enhancement".

Yes, that's why I recommend to look out Abiword's approach.
Comment 13 philipp.lohmann 2008-07-16 12:33:36 UTC 
due to limited resources we'll have to retarget this one
Comment 14 hdu@apache.org 2008-12-09 15:13:07 UTC 
with fontconfig etc. being active the interaction of this patch with the current version is non-trivial
Comment 15 Marcus 2017-05-20 11:31:20 UTC 
Reset assigne to the default "issues@openoffice.apache.org".
