[comp.text.tex] hyphenation in TeX 3.0?

geyer@galton.uchicago.edu (Charles Geyer) (10/27/90)

The TeX 3.0 we have here performs the following terrible hyphenation:
in response to \showhyphens{Younes} it echos

 \tenrm Y-ounes

and splits the word as shown across a line break, while TeX 2.9 echos

 \tenrm Younes

and refuses to break the word, which is right.

Do we have a broken installation of 3.0 or is 3.0 itself broken?  If
the answer isn't obvious, what other attempts could be made to diagnose
the problem?

You are probably using an old version of plain.tex.
The length of the hyphenated fragments is controlledby
two new parameters in TeX 3, \lefthyphenmin and \righthyphenmin.
These have probably a default 1, but are set to 2 and 3
respectively in the plain format. If you are not in a position
to recreate your format (complain fiercely to your systems crew,
because they messed up!, but in the mean while)
include statements
\lefthyphenmin=2 \righthyphenmin=3
in the jobs where this occurs.
