Pascal,

That is a great trick, thanks!

Ok so I think the only way out it to pre process my xml
file to mark
special characters so that I can them easily find them in my xsl
document.
Good idea if that's possible.
Could another option be to find a font that contains all unicode
characters?
Sure, if such a beast exists.
How difficult is it to embed a special font that would work both on
Mac and PC? Do you have any pointers on how to do this?
Simply get a PC-compatible font. It should also work on the
Mac since FOP doesn't use the Mac's font system in case of
PDFs. If you have such a font simply follow the instruction
for custom fonts. HTH
Thanks,

Oops, sorry. Hmm, you've got a problem there. That's actually
something that would (in theory) be handled like this:
<fo:inline font-family="Helvetica, ZapfDingbats">Some
text â˜… More
text</fo:inline>
FOP should (again in theory) automatically switch to
ZapfDingbats if
Helvetica doesn't contain a character. The problem is that FOP
doesn't do that, yet.
Working around this in XSLT is next to impossible (I
think), which
leaves a special preprocessor that inserts special fo:inlines as
necessary but in this case you could just as well try to
implement
that directly in FOP. It'll not be so simple.

Hi,
This is not really what I am trying to achieve. I know
that I can
handle special characters using the ZapfDingbats font.
However what
I don't know to do is parse a text content to encapsulate
<fo:inline> element each time such a special character is found.
So tranforming:
"Some text â˜… More text"
To:
<fo:inline font-family="Helvetica"> Some text  <fo:inline
font-family="ZapfDingbats">â˜…</fo:inline> More text </fo:inline>

Hi,
I need to display in a pdf file some text that
contains different
type of characters: some are ascii type but other are special
ones like the 'star' or 'square' characters. I understand from
what I have read that those special characters are not
available
in the default Helvetica or Courier base font and that
I need to
use the ZapfDingbats font.
So what I need to achieve is transform the following
XML content:
"Some text â„¢Ëš More text"
Into:
<fo:inline font-family="Helvetica"> Some text  <fo:inline
font-family="ZapfDingbats">â„¢Ëš</fo:inline> More text
</fo:inline>
How can this be done using XSL to create the proper FO
document
knowing that I don't know in advance what the text to
translate
looks like and how many 'special' characters it contains (ex
'asdfâ„¢Ëšasâ„¢Â¡dfâ„¢Ëšasâ„¢Â£dâ„¢Ë›â„¢Æ’fasdâ„¢Ëš')
Thanks for any tips!
