System.Text.Encoding - GetBytes()

GetBytes() (a static method of System.Text.Encoding) converts a string to a byte array.

The following script prints different output, depending the encoding of the file and if it is run with PowerShell 5 or PowerShell 7

$enc_utf_8   = [System.Text.Encoding]::GetEncoding('utf-8'     )
$enc_latin_1 = [System.Text.Encoding]::GetEncoding('iso-8859-1')

write-host 'Bytes in UTF-8'
foreach ($b in $enc_utf_8.GetBytes('René')) {
   write-host "  $b"
}
write-host 'Bytes in Latin-1'
foreach ($b in $enc_latin_1.GetBytes('René')) {
   write-host "  $b"
}

For the following conditions:

Powershell 5, Script is Latin-1
Powershell 5, Script is UTF-8 with BOM
Powershell 7, Script is UTF-8

the output is:

Bytes in UTF-8
  82
  101
  110
  195
  169
Bytes in Latin-1
  82
  101
  110
