How to prevent line break when hyphenation is enabled?
Hi,
is there a way to prevent a line break inside a word, when hyphenation
is enabled?
I've tried two things, but neither of them did the trick:
1. Insert WORD JOINER characters (Ux2060) between all characters of the word
2. <fo:inline keep-together.within-line="always"/>
I'm attaching a sample fo file, in case somebody wants to give it a try.
Thanks & Regards,
Matthias Reischenbacher

Hi,
just in case somebody else has this problem: I ended up wrapping every
single character inside a fo:character element and set the hyphenate
attribute to false. This also prevents hyphenation and doesn't require
the Arial Unicode MS font.
e.g.
<fo:character hyphenate="false" character="C"/>
<fo:character hyphenate="false" character="A"/>
<fo:character hyphenate="false" character="N"/>
<fo:character hyphenate="false" character="o"/>
<fo:character hyphenate="false" character="p"/>
<fo:character hyphenate="false" character="e"/>
<fo:character hyphenate="false" character="n"/>
I'm still wondering why XSL-FO doesn't allow the hyphenate attribute on
fo:inline elements....
Regards,
Matthias Reischenbacher

Interesting site. When you click on the link 'Local fonts', you see
that some fonts have this glyph for the zero-width joiner. I guess
those fonts focus more on insight in the character string than on
rendering texts.

Thanks for pointing into this direction. Using the ZERO WIDTH JOINER
prevents hyphenation. I had to use Arial Unicode MS font in order to not
get the "unknown glyph" error.
What is kind of strange although, when using some other font, which also
contains this character (e.g. Arial, Calibri, Times New Roman etc. [1]),
the character gets displayed in a weird way (have a look at the attached
screenshot).
I'd prefer to use Arial because it's a Windows standard font, but if
that's not possible I'm happy with the current solution too. Which part
of the FOP code is responsible for drawing this character in PDF output?

Any non-word character prevents hyphenation. Word characters are
defined in the classes element in the source hyphenation file. For
German these are a-z, ä, å, ö, ü and ß. WORD JOINER is not one of
them, but apparently it is filtered out. I tried ZERO WIDTH JOINER,
but that is rendered as an 'unknown glyph' #.
