Text Formatting ⇒ add hyphenation rules? (polyglossia)

[Laurentius]

Is it possible to add hyphenation rules, for example never to split the combination aa?

[west.logan]

I am not aware of a (easy) way to adjust the hyphenation rules. If it is only one where the problem is occurring then you could of course just use the

Code: Select all

\hyphenation{xxx-aas-xxx}

and select where you want to allow breaks.
If it is another language that contains double a's and you want a global definition for hyphenation rules, then I don't know.
