Add brazilian portuguese wordlist to BIP39

[kuthullu]

The wordlist consists of 2048 non offensive, manually picked brazilian portuguese words.

Also edited the README with a small note about the work done.

[prusnak]

I don't care about this lists. The only list I support is the English one.

[guilhermep]

I think this list should not contain words in common with the other wordlists, following the precedent set by the spanish, italian and french lists and maintaining the possibility to detect the language with just one word.

[brenorb]

I suggest changing the word "abdome" and other words which have more than one possible orthography in portuguese.

[johnnyasantoss]

Is there any progress with this PR?
I agree with @brenorb argument about having words that may cause confusion.

[luke-jr]

One or more of the authors is needed to approve any modifications.

[brenorb]

I had no time to review the entire list, but this contribution seeks to pointing some words which might cause some confusion in Portuguese language.

I suggest discarding these ones and others which might have a similiar problem and picking new ones.

[brenorb]

I suggest changing words like "abdome" which can be written in more than one form, and words like "acento", which sounds identical to "assento".

[brenorb]

Sounds very similar to "bravo", which is widely more used.

[brenorb]

Sounds identical to "cocha".

I worked some weeks in kuthullu's list to fix these issues and submitted a pull request #720 now with these rules:

1. Length between 4 and 8 characters.
2. Words can be uniquely determined typing the first 4 characters.
3. No accents or special characters.
4. No complex verb forms.
5. No plural words, unless there's no singular form.
6. No words with common double spelling, except when the only change is the accent.
7. No words with the exact sound of another word with different spelling.
8. No offensive words.
9. No words already used in other language mnemonic sets.
10. The words which have not the same spelling in Brazil and in Portugal are excluded.

@successhalf, asking once is enough. You asked the exact same question 4 times. I've responded to you in iancoleman/bip39#261

@brenorb you ready to restart the wordlist optimization project?

[brenorb]

@brenorb you ready to restart the wordlist optimization project?

Well, @DonaldTsang, it's already done right here: #720
What are you planning?

[tonnon]

Any updates to add the Portuguese wordlist?

Any updates to add the Portuguese wordlist?

It's been a year waiting for reviews. It's all done here: #720

[johnnyasantoss]

Who can review that? I don't know any core dev that speaks/understands Portuguese.

No one needs to be a core dev to review this PR. If you speek Portuguese I deeply encourage you to review it and leave a comment so they can properly accept or reject the PR.
