Changing priority from 1 to 3. Font in 1.1.5 looks different, better. Reassigned.
I think the appearance of the words is the most important. So the Priority should is P1.
What is seen in a presentation depends strongly on the Canvas type, which is dependent on the OS. Which OS is involved here? I'm not seeing much of a difference. Is it possible to attach screenshots of the different appearances?

get the attachment with Openoffice.org_m165 running on windows2000
Thanks for the screenshot. I see that some characters are darker than their neighbouring characters. Do you mean with that with "looks different"?
It is not only darker. The font of the characters in this file dose not exist in my OS, so soffice replaces this font with a font that exist in my OS. Some characters' font is replaced with font A, and their neighbouring characters' font is replaced with font B. All of the characters have the same font. But they are repleased with two or more fonts that exist in my OS. And it is more difference when slideshowing. This is the problem.

Thanks for the second screenshot that shows the problem much better. The problem is that the fonts specified in the document ("cwTeX 粗黑體" and "標 楷體") are not directly available on the platform and that no explicit fallbacks are set. You could do this by setting the font in the presentation to e.g. "cwTeX 粗黑體;pmincho" if pmincho is a font that looks similar to the cwTeX font. This would solve the immediate problem with the presentation. If the cwTeX font is a often used it would also be a good idea to know their relationship with other common fonts. How would they map to the fonts on a standard Windows install? Could you provide such a mapping? Since OOo doesn't know anything about the cwTeX fonts and their fallbacks yet, it just picks a font that has a reasonable chance of replacing it. If this font doesn't support all the characters required for the text another font has used to show something reasonable. This is what you are seeing. In order to pick a better replacement font in the first place the mechanisms I mentioned in the paragraphs above should be able to run once you provided the mapping between the cwTeX fonts and their commonly used counterparts.
Openoffice picks a font to replace the font("cwTeX 粗黑體" and "標楷體"), it is a right way. But the bug is: It replace some characters(with font "cwTeX 粗黑體" and "標楷體") to font A and replace the neighbouring characters(with font "cwTeX 粗黑體" and "標楷體" too) to font B. It should replace all characters(with font "cwTeX 粗黑體" and "標楷體") to one type font but two or more types fonts. Such as there are some characters with the same font that not existing in OS,but one part of the characters is replaced with font A and another part is replaced with font B. It is wrong.
> Openoffice picks a font to replace the font("cwTeX 粗黑體" and "標楷體"), it is a right way. But what if this replacement font doesn't contain all the characters that are later needed in the presentation? Would you prefer to see empty rectangles instead of readable symbols?
The right result is that all characters with the same font in the document are replaced with 'only one type' font.
Retargeted due to developer demand.
Reset assigne to the default "issues@openoffice.apache.org".
