![]() Is this just 'the way it is' when B64 encoding UTF-16LE, or is there some other way I can convert this into a smaller B64 representation that will still be understood by powershell. If it were normal Base64 size it would be fine, but it's easy for me to overrun the limit when it's doubled like this. This is causing issues with running this script thru some remote tooling (which calls powershell -EncodedCommand) which I think is imposing a cmdline character limit. ![]() But when I encode it as above (I think because of the UTF16-LE representation as 2-byte characters?), the size of the Base64 encoded script is about double the size of a 'normal' Base64 encoding because every character in the script gets converted to a Base64ed "original character + NUL character". The original script itself is a little less than 3000 chars. Powershell -EncodedCommand "$Base64Script" $Base64Script = ::ToBase64String(::Unicode.GetBytes($ScriptContent)) Use the following command to execute the encoded command. $ScriptContent = Get-Content -Raw -Path Path_To_Script.ps1 On the Start menu, open an application named: Windows PowerShell.
