`:::I am Portuguese, and so, Portuguese is my native language. O nome do ladrão incógnito foi descoberto pelos tradutores que pediram à editora inglesa que revelasse se era um homem ou uma mulher, por uma questão de pronomes. Quando a resposta voltou espantaram-se os tradutores por ver que Londres lhes tinha dado um nome. O ladrão que assina R.A.B. é Regulus Arthur Black, irmão de Sirius Black, o padrinho de Harry. Para quem segue a história é um dado importante.  The name of the unknown thief was discovered by the translators who asked the english publisher to say if it's a man or a woman [I don't know how to translate this. The reason they asked that, is that in Portuguese, when you are referring to a man (homem), you say ``O homem``. When you are referring to a woman (mulher), you say ``A mulher``. O/A is how you know that you are talking about a man or a woman. The publisher needed to know how to call him/her]. When the answer arrived, the translators were surprised when they saw that they were given a name. The thief who signs ``R.A.B.`` is Regulus Arthur Black, brother of Sirius Black, Harry's godfather (i think it's this). For those who follow the story, it's an important detail.  I hope this helps understanding the article ) By the way, Portuguese is very different from French and Spanish. Please don't confuse them, as many people don't like that ;) we're small, but too big to be confused this way.    `
