Problems with encoding

[yuzhaninan]

When executing GET requests, the response is received in UTF 8 encoding, but the Cyrillic character "х" cannot be processed correctly. Thus, it is necessary to use in the POST and PATCH methods the conversion of this character to another. How can this be won?
Have to use

What PowerShell release do you are using ?

[yuzhaninan]

5.1

[alagoutte]

do you have try with PS 7 ?

[yuzhaninan]

Not everything for 5.1 is compatible with 7
Implemented part of the code in Powershell 7
The result is the same. I read that in 7 they fixed the choice of encoding for the Invoke-RestMethod cmdlet response. (in 5.1 hardcoded UTF-8)
In Powershell 7

'ЦÑ^ÃÑ^Åникиди ЮÑ^Àий Ð^ßеÑ^ÂÑ^ÀовиÑ^Ç' | Fix-Encode
Цухникиди Юрий Петрович
$TO = 'UTF-8' ; $From = 'ISO-8859-1'
$response = 'ЦÑ^ÃÑ^Åникиди ЮÑ^Àий Ð^ßеÑ^ÂÑ^ÀовиÑ^Ç'
[System.Text.Encoding]::GetEncoding($TO).GetString(
[System.Text.Encoding]::GetEncoding($From).GetBytes(
($response | ConvertTo-Json -Depth 10)
))
"Цу�\u0085никиди Юрий Петрович"

I had the same problem with Cyrillic and Greek charsets.
I fixed it by replacing Invoke-RestMethod with Invoke-WebRequest in Functions/Helpers/InvokeNetboxRequest.ps1.
Like that:

$splat = @{
        'Method'      = $Method
        'Uri'         = $URI.Uri.AbsoluteUri # This property auto generates the scheme, hostname, path, and query
        'Headers'     = $Headers
        'TimeoutSec'  = $Timeout
        'ContentType' = "application/json; charset=$([System.Text.Encoding]::Default.WebName)" # <--- This line is modified 
        'ErrorAction' = 'Stop'
        'Verbose'     = $VerbosePreference
    }
...

# $result = Invoke-RestMethod @splat # <--- instead this line I use three lines below
$Response = Invoke-WebRequest @splat
$reader = New-Object System.IO.StreamReader($response.RawContentStream, [System.Text.Encoding]::UTF8)
$result = $reader.ReadToEnd() | ConvertFrom-Json
