Diaeresis to be dropped after hyphen in Dutch

[RM f/g]

Here’s a little something to improve the Dutch language setting. It may apply to other languages as well, who knows. It's present in inDesign, but not yet in Publisher, I noticed.

With hyphenation, the diaeresis is dropped if it comes immediately after the hyphen. In this case, the diaeresis is superfluous because the hyphen already indicates that a new syllable follows.

ruïne
ru-
ine

deltaïsch
delta-
isch

creëren
cre-
eren

English used to do that too, when words like cooperate, reentrant, etc. were spelled with a diaeresis on the second vowel. We seem to have "solved" this problem by dropping the use of diaeresis in general  

Your suggestion seems like a good one.

I didn't know this about Dutch or English! This sounds like a good feature request.

I went looking for more information and found this interesting paper from OpenOffice: https://tug.org/TUGboat/tb27-1/tb86nemeth.pdf

Page 2 has a good table that lists similar issues for other languages. For example, Zucker in German because Zuk- ker.

The document goes on to provide the hyphenation patterns required to support these exceptions.
