[xep-support] Problem with greek characters in chapter titles using some fonts

[Alexander Peshkov]

Hello Marc,

I believe this problem has nothing to do with XEP itself but rather
caused by XSLT (customization or native Docbook stylesheets) which
generate inadequate XSL FO. Could you please send me a problematic XSL
FO file?

Best regards,

MB> Nikolai,

MB> thank you for your comments, but this does not fit with what I
MB> observe:

MB> in the *BODY* of the text *EVERYTHING* is fine with the greek
MB> characters, whatever font I choose (Palatino, Helvetica,
MB> BookAntiqua ...).
MB> It is *ONLY* in the *TITLES* that I have problems.

MB> So I do not think it is an inherent problem with the fonts.
MB> Because even if Helvetica does not cover the greek alphabet,
MB> the docbook 1.62.0 stylesheet generated fo code should tell
MB> XEP to fall back on other fonts (which seems to work fine for
MB> the body of the text):

MB>   font-selection-strategy="character-by-character"
MB>   font-family="Helvetica,Symbol,ZapfDingbats"

MB> My feeling is rather that maybe XEP does not honour these
MB> settings for titles for some reason ???

MB> Any hints on this are greatly appreciated,
MB> Marc
