Questation about powershell and encoding

Question

hi all,
sorry for my englisch . i have questaton about abou file encoding . I have file with ISO-8859-2 . But if I call in the powershell funkcion OpenText , the currentencoding is UTF8 . How i change it ? The file is large and if I try opent with get-content the
file is open about hour.... thanx

 ISO-8859-2 is not an encoding it is a character set.  Files do not specify character sets.  Character sets are specified by a system or by a document such as an HTML or XML document.
I believe that ISO-8859-2 is the default Windows Central European character set. It is known as Latin II.  ISO-8859-1 is Latin I and is what is used in US Windows.  (See:
http://en.wikipedia.org/wiki/ISO/IEC_8859-1)
Out-File and other file creation commands have an uncoding which determines how the characters are stored.   The default for Windows 7 and later is Unicode.

ISO-8859-2 can be stored in any encoding except ASCII-7 as it is only 8 bits.  Windows always stores ASCII-7 as ASCII.
All Unicode encodings can store ISO-8859-2.
Here is the ISO-8859 to Unicode  spec:

¯\_(ツ)_/¯
I'm not sure it's a good idea to make the distinction between a character set and an encoding here.  When it comes to interpreting the bytes in a file, those two concepts are linked.  Even though Unicode encoding can be used to represent every
character that ISO-8859-2 can represent, they don't always have the same byte values.  This code outputs their 57 differences:
$iso8859_2 = [System.Text.Encoding]::GetEncoding('ISO-8859-2')
$differences = for ($isoCode = 0; $isoCode -lt 256; $isoCode++)
$isoString = $iso8859_2.GetString($isoCode)
$unicodeBytes = [System.Text.Encoding]::Unicode.GetBytes($isoString)
$unicodeCode = [System.BitConverter]::ToInt16($unicodeBytes, 0)
if ($unicodeCode -ne $isoCode)
[pscustomobject] @{
Character = $isoString
ISO8859_2_Code = $isoCode
Unicode_Code = $unicodeCode
