Dictionary files <pt_BR.dic> & <pt_BR.aff> not recognized.

[leodrivera]

Description

Dictionary files <pt_BR.dic> & <pt_BR.aff>, from the LibreOffice and Chromium, are not recognized nor loaded as online dictionaries.

Reproduce

I've tried both as online and offline dictionaries:

• On the online attempt, used the following config in SpellChecker settings, under JupyterLab.

  [
      {
          "id": "pt_BR",
          "aff": "https://raw.githubusercontent.com/LibreOffice/dictionaries/master/pt_BR/pt_BR.aff",
          "dic": "https://raw.githubusercontent.com/LibreOffice/dictionaries/master/pt_BR/pt_BR.dic",
          "name": "Português (Brasil)"
      }
  ]
  
  

  When I try to load the dict, it keeps eternally showing Loading dictionary…

  I also tested using the dict that is shown in the example, and it worked correctly:

[
    {
        "id": "en_US-online",
        "aff": "https://cdn.jsdelivr.net/codemirror.spell-checker/latest/en_US.aff",
        "dic": "https://cdn.jsdelivr.net/codemirror.spell-checker/latest/en_US.dic",
        "name": "My favorite variant of English"
    }
]

• On the offline attempt, I followed what is described in the README
  After adding the these 2 files (pt_BR.aff and pt_BR.dic), no new dictionary appeared. Tested with the files from both LibreOffice and Chromium repos.

Expected behavior

That the dictionaries were loaded correctly, both by the "online" and "offline" method

OK, that is understandable ... The reason is that the underlying spellcheck engine has a lot of problems with the aff-files in the case of roman languages with a lot of differentiations due to grammar rules. I had the same problem with the italien dictionary I found for free. The engine is simply enrolling all rules into a list of words, which is huge in your case ;-) we are looking for a better engine which also will solve some other problems, e.g. multi/mixed languages support.

@ocordes
You said on the last comment that you guys were looking after a new engine. Since it has passed almost 3 years and a lot of contributions were made since them, do we still have this issue?
