Did I say that the source code of FOP is available? :-) So there is a feature in PDF to store the actual content as UTF-8 without the font embedded, and to tell the PDF viewer to use whatever fonts it can find to render the document? Because that's what we really need to solve the problem. I know that Acrobat can replace non-embedded Type1 fonts so I believe it should be possible for TrueType, too. FOP is probably not even far from supporting that. It's probably only about a few details, but then I'm not the specialist on TrueType fonts in PDF. I'd have to dive in a lot further to make a really usable statement in this regard. But! I don't know how far this font substitution goes. Using whatever fonts it can find is probably stretching the reality considerably. I think there are some standard to do font substitution but I have never worked with them. Particularly in our system, we can't guarantee that the person generating the PDF has the same fonts as the person reading it. And worse, we can't even guarantee that the person generating it has ARIALUNI.TTF (as it's not freely redistributable.) So embedding fonts in any fashion doesn't solve the problem, and neither does font substitution at the time of generation. In such an environment it is normally by far the best solution to embed the font. You just need to find fonts that you can redistribute in embedded form. But you may need to buy licenses. I was thinking that the lack of font substitution at the time of rendering was more of an issue with PDF, but if you say it's an issue with FOP then I'll take your word for it because I don't know PDF well at all, just its damage to society. :-) Damage to society when not using font embedding, yes. :-) If you can't control the target environment you're bound to run into problems if you don't embed fonts. Sad reality. I believe that font substitution will only 95% of your problems. Jeremias Maerki - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: creating a PDF document containing UTF-8 characters
Thank you Jeremias, I followed the instructions and now I can make it work by embedding the font in the document. Looking at the samples in userconfig.xml, this is how I register the fonts: font metrics-file=ttfarialuni.xml embed-file=C:\WINDOWS\Fonts\ArialUni.ttf kerning=yes font-triplet name=ArialUni style=normal weight=normal/ font-triplet name=ArialUni style=normal weight=bold/ font-triplet name=ArialUni style=italic weight=normal/ font-triplet name=ArialUni style=italic weight=bold/ /font /fonts What happens if I omit the embed-file tag?

Re: creating a PDF document containing UTF-8 characters
You simply need to get a TrueType font that contains the necessary characters. Create the font metrics file and add it to the configuration as shown in the documentation. You can then simply specify font-family=MyJapaneseFont on the fo:root element. It is automatically inherited by all child elements. On 30.08.2005 21:13:22 Melih Ovadya wrote: Thank you for this info.
