Using @mawiesne 's French pull request #580 as reference, while looking at the Spanish abbreviation code. The current commit will not compile. I had to stop (tis' new year!), but will finish it later, edit the commit, update the title, etc. 👍

Thx @kinow - could you rebase so that PT fits on top of FR changes?

Nice PT text sample! Code-wise everything looks fine. abb_PT.xml is our largest abb dict so far, wow 🚀!

One of my examples failed returning a token as word,, so I added this extra replace in this test 👍

Done! Tests passed locally for me.

Easier after the code base has been cleaned up a few times, and especially having some recent examples like the Fr (and also have reviewed the previous PR's you added for other langs). Thanks!!!

abb_PT.xml is our largest abb dict so far, wow 🚀!

🎉 we have everything from the Brazilian Academia de Letras, plus n.° that was missing, I believe 🎉
