The history of luaTEX 2006–2009 / v 0.50 - Pragma ADE

When testing the implementation we ran into cases where the initial t showed up wrong,
for instance in the the Dutch word troef. Because space can be part of the rules, we
need to handle the cases where words end and start and boxes are then kind of special.
troef troef troef troeftroef troef \par
\ruledhbox{troef troef troef troeftroef troef} \par
\ruledhbox{troef 123} \par
\ruledhbox{troef} \ruledhbox{troef } \ruledhbox{ troef} \ruledhbox
{ troef } \par
oe oe tre fe oe
oe oe tre fe oe
oe 123
oe
oe
oe
oe
Unfortunately, this does not work well with punctuation, which is less prominent in the
rules than space. In our favourite test quote of Tufte, we have lots of commas and there
it shows up:
review review review, review \par
itemize, review \par
itemize, review, \par
re rw rie, rie
ize, rie
ize, rie,
Of course we can decide to extend the rule base at runtime and this may well happen
when we experiment more with this font.
The next one was one of our rst test lines, Watch the initial and the Zapno ligature.
