Concatenate . html files into a . htm with Powershell

Question

So, I need to concatenate thousands of . html files to just one . htm, there’s already a file. batch that does this for me, using the following code:

#type *.html > output.htm

@echo off

for /r %%i in (*.html) do (

    if not %%~nxi == output.htm (

        echo %%~nxi >> output.htm
        type "%%i" >> output.htm
        echo. >> output.htm
    )
)

What happens is that this process is extremely slow, I found that with Powershell is faster and I tried to create the code, but I know very little of languages, it was like this:

get-content *.html | Set-Content output.htm

Beeeeem simple! Even worked out, the problem is that some characters get "corrupted", as in the text below:

O ICMS de responsabilidade das empresas industriais fabricantes de calçados 
que usufruam do crédito presumido previsto no inciso XXIX do artigo 57 do 
RICMS/SE, é diferido no recebimento do exterior ou, relativamente à 
diferença de alíquotas, pelas aquisições em outra unidade federada de 
máquinas, equipamentos, ferramental, moldes, modelos, instrumentos e 
aparelhos industriais e de controle de qualidade, e seus sobressalentes.

I tried to leave the code like this:

get-content *.html | Set-Content output.htm -Encoding UTC8

and tried to change the code to others and tbm didn’t work.

Can someone help out?

Possibly there may be multiplicities of encoding in the content of your html files, I suggest testing using -Raw and replace -Encoding UTC8 for String:

---

Get-Content -Raw *.html | Set-Content output.htm -Encoding String

---

or still using alias

---

cat -Raw *.html | sc output.htm -Encoding String
