	Re: DO NOT REPLY [Bug 48108] Special Characters are not rendering by Arjun Priyananth :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi Jeremias, In my xml arrow and tilde is there as text not as code. in fop file it shows as xml and i am not using any specific fonts. those symbols are there in "Symbol" fonts. Then why its not shown in PDF? Since you have suggested inline tags. How do i get that in fo file. It doesn't put inline tag for arrow, tilde and for some charcters like "ö" (instead of two dots put a hypen on the top). This is the steps I followed - I took one xml which has alpha char, tilde char & arrow char. - transfored to FO. in the fo there is no inline tag for tilde and arrow. alpha has that. how can i get that inline for those two Thanks & regards, Arjun On Tue, Nov 3, 2009 at 1:15 PM, <bugzilla@...> wrote: https://issues.apache.org/bugzilla/show_bug.cgi?id=48108 Jeremias Maerki <jeremias@...> changed: What \|Removed \|Added ---------------------------------------------------------------------------- Status\|NEW \|RESOLVED Resolution\| \|INVALID --- Comment #1 from Jeremias Maerki <jeremias@...> 2009-11-02 23:45:46 UTC --- Please see the following FAQ entry: http://xmlgraphics.apache.org/fop/faq.html#pdf-characters If the font you're using doesn't have the necessary glyphs, FOP can't make them appear.

	Re: DO NOT REPLY [Bug 48108] Special Characters are not rendering by Jeremias Maerki-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi Arjun, I'm not sure I understand everything that you're saying. I'll try to explain this from my point of view. Let's first look at the glyphs: The tilde: in Unicode 0x007E, TILDE This character is part of the US-ASCII 7-bit encoding, so most fonts have that. However, the Symbol font doesn't have the 0x007E glyph. Instead, it has the glyph for Unicode 0x223C, TILDE OPERATOR. So these are really two different glyph although looking similar, but with a different function. Arial Unicode MS has actually both variants, but they look different. The arrow: in Unicode 0x2192, RIGHTWARDS ARROW The latin base 14 fonts (Helvetica, Times and Courier) don't have that glyph. Symbol does have it. Arial, too. The alpha: in Unicode 0x03B1, GREEK SMALL LETTER ALPHA You'll notice that this glyph is available in Symbol and most TrueType fonts, but not the base 14 Helvetica, for example. Please see the attached FO file which plays through all discussed glyphs. Each once using the direct character and once using a character reference (in the form �). Both forms are equivalent. What's easier to choose depends on the way your content is created. So, how to get these character into the FO? That depends largely on your application. You have to control either what characters you generate or which fonts you choose. Unfortunately, FOP doesn't support glyph-by-glyph selection of fonts, so just specifying a font list on the font-family property doesn't always help because FOP currently only splits at word boundaries (I think). What you can try is to envelope certain characters in fo:inline or fo:character tags using XSLT. But that's obviously just a work-around for the FOP limitation if you have such a wide range of characters coming in. Instead you can try to use a different font that has a wider range of glyphs like Arial Unicode MS or DejaVu Sans. That would make such stunts unnecessary. I hope that helps.

I'd enhance the stylesheet you use to transform the XML into XSL-FO. That would be the right place to handle such things. I don't think it makes sense to pre-process the XML. > For your other suggestion : > If possible could you please tell me how to envelope fo:inline only for > certain characters in XSLT. Take a look at the following page for inspiration: http://www.dpawson.co.uk/xsl/sect2/N7240.html (particularly example 8 and 9) Not exactly what you will need to do but close enough. > Also herewith I have attached the PDF for the glyphs fo you have sent to me. > Could you please tell me whether I am missing any fonts. I assume you simply haven't done any font configuration, yet. So if you're just using the default font, consider switching to a font like Arial Unicode MS or DejaVu Sans. The default fonts simply don't have a big range of glyphs available. You may be able to avoid the special processing altogether. For configuring fonts with FOP, please see: http://xmlgraphics.apache.org/fop/0.95/fonts.html Once you configured additional fonts, try them with my glyphs.fo file to see the difference.

I'd enhance the stylesheet you use to transform the XML into XSL-FO. That would be the right place to handle such things. I don't think it makes sense to pre-process the XML. > For your other suggestion : > If possible could you please tell me how to envelope fo:inline only for > certain characters in XSLT. Take a look at the following page for inspiration: http://www.dpawson.co.uk/xsl/sect2/N7240.html (particularly example 8 and 9) Not exactly what you will need to do but close enough. > Also herewith I have attached the PDF for the glyphs fo you have sent to me. > Could you please tell me whether I am missing any fonts. I assume you simply haven't done any font configuration, yet. So if you're just using the default font, consider switching to a font like Arial Unicode MS or DejaVu Sans. The default fonts simply don't have a big range of glyphs available. You may be able to avoid the special processing altogether. For configuring fonts with FOP, please see: http://xmlgraphics.apache.org/fop/0.95/fonts.html Once you configured additional fonts, try them with my glyphs.fo file to see the difference.
