Most of hyphenation in Portuguese splits sylables from two consonants in a row (r-r, s-s Ex: 'car-ro', 'profis-são'), but this is not true for nasal sounds formed with the letter H (lh, nh) and I see myself having to review this hyphenation constantly. For example, the correct hyphenation is 'traba-lho', but inDesign usually hyphenates 'trabal-ho' (which is incorrect). It is a simple addition to the program that could save a lot of reviewing time.
There are some other issues too.
Could you please check that out and review the hyphenation rules as of grammar? Portuguese has quite a bit of peculiar ruler, but it will be worth it! I am using the Portuguese Brazilian dictionary.
