HTML com UTF-8-pt-br (CGI-Bin)



Um servidor com o Microsoft Windows Server e o IIS (Internet Information Services) instalado, nele vem como padrão de instalação reconhecer o texto do HTML no idioma inglês. 

Recentemente, tive problemas de meu código HTML parar de reconhecer os acentos utilizados do idioma português-brasileiro.  Tentei de tudo, e nada fazia os acentos voltar a funcionar. Pesquisei em dois livros velhos de HTML da década de 80, e lá tinha um capitulo falando de CGI, então eu resolvi fazer um arquivo CGI para testar, e funcionou, a acentuação das palavras voltaram a funcionar perfeito novamente no HTML.

Caso algum de vocês passem pelo mesmo problema que eu, podem testar esta solução.






Esse arquivo paginacao.cgi tem que ser feito o upload para dentro do servidor web.

Criei um arquivo CGI-Bin chamado paginacao.cgi com o seguinte conteúdo abaixo, ele funcionou perfeito:

#!/bin/sh
Content-type: text/html
Language: pt-br
Charset: UTF-8-pt-br

========================================================================

Translation:

A server that has Microsoft Windows Server and Internet Information Services (IIS) installed, it is by default that the installation recognizes English-language HTML text.

I recently had problems with my HTML code failing to recognize the accents used in the Portuguese-Brazilian language. I tried everything, and nothing made the accents work again. I researched two old HTML books from the 80's, and there was a chapter talking about CGI, so I decided to make a CGI file to test, and it worked, the accentuation of the words came back perfect working again in HTML.

If any of you go through the same problem as me, you can test this solution.
This paginacao.cgi file has to be uploaded to the web server.

I created a CGI-Bin file called paginacao.cgi with the following content below, it worked perfect:

#! / Bin / sh
Content-type: text / html
Language: pt-br
Charset: UTF-8-pt-br

=======================================
Very interesting compilation published here, with a strong machine learning flavor (maybe machine learning book authors — usually academics — are more prone to making their books available for free). Many are O’Reilly books freely available. Here we display those most relevant to data science. I haven’t checked all the sources, but they seem legit. If you find some issue, let us know in the comment section below. Note that at DSC, we also have our free books:

Windows Server: Microsoft Visual C++ (64 bits)

Para o Microsoft Windows Server versões 2008 / 2012 / 2016 poderem funcionar melhor, deve-se fazer o seguinte:


Observação:  Comprei meses atrás na Microsoft Press, diversos livros do Microsoft Windows Server 2012 R2 (2 livros) e do Microsoft SQL Server 2012 (3 livros), os quais eu ainda não terminei de ler.  


Sendo que no livro do exame do Microsoft Windows Server 2012 (Exam Ref 70-410 - Installing and Configuring Windows Server 2012 R2 - Author Craig Zacker), o autor do livro recomenda não existir drivers de 32 bits (x86) instalado dentro de um sistema operacional de 64 bits.  Nesse livro ele diz que esses drivers de 32 bits (x86) tem que ser bem eliminados (desinstalados) no sistema operacional de 64 bits (x64). E nesse livro, ele também informa que o sistema operacional Microsoft Windows Server desde a versão 2008 é versão 64 bits (x64).  
Processador 32 bits x 64 bits
Eu notei que existe drivers de 32 bits (x86) instalados dentro de diversos computadores com o sistema operacional de 64 bits (x64), como por exemplo: Microsoft Windows Server 2008 / 2012 / 2016, Microsoft Windows 7, Microsoft Windows 8 e Microsoft Windows 10.


Caso exista instalado no servidor o sistema operacional Windows 64 bits instalado (ou exista instalado em computador de usuário comum) algum aplicativo com drivers versão 32 bits (x86) do Oracle Java ou do Microsoft Visual C++ 2005 / 2008 / 2010 / 2013 / 2015, etc, instalados, o técnico precisa fazer o download da versão de 64 bits deles, depois disso feito instalar um a um esses drivers 64 bits (x64), porque somente assim a desinstalação dos drivers de 32 bits (x86) conseguirá fazer ser concluída com sucesso, e por último reinicia o computador/servidor.  


Somente estando com os drivers de versão 64 bits instalados, é que o sistema operacional de 64 bits (x64) irá funcionar melhor.  Idem quanto aos computadores dos usuários comuns.  No site da Oracle existe o driver do JAVA versão 64 bits disponível para download.


Segue abaixo os links para download e instalação dos drivers do Oracle Java e do Microsoft Visual C++
