Translated isAlpha()

[robsoncouto]

There seems to be something wrong with the example code tough.
It seems to be testing is a variable is alpha, but says to the user that is is alphanumeric.
May need fixing.

you are right @robsoncouto, I opened an issue about that in the -en repo, you can fix it here in pt, thanks!

No problem :)
I noticed there is something similar in https://cdn.arduino.cc/reference/en/language/functions/characters/isdigit/
The comment say "tests if this is a letter" when it tests if the variable is a number. I fixed that one already here, as the problem was in the comment, not the code itself.
There may be other bugs like this in the other character functions I have not translated yet.

Please check the last commits in reference-en, we fixed many broken links. If, when you translate a page, you could check if all the links in the page are ok, it would be really great. Thanks so much

Hi @smellai . I find it quite hard to keep focused in the translation and fix the broken links at the same time. For now I will keep up the translation and add an issue for the broken links.
