Re: [XeTeX] Follow-up to previous mail about hyphenation

[Yannis Haralambous]

Even when I reset \catcode to 11, the behavior is the same. Only Arabic words containing ^^^^200d are not hyphenated, others are hyphenated as expected.

The other mystery is why Arabic words seem to only be hyphenated once.

I should get at least one hyphenation in each word, no? My guess is that polyglossia (or something else in latex?) thinks it knows best how to handle U+200D and is getting in your way.
