How to encode string to Unicode Powershell

Question

I need to convert a string characters to unicode.

To be simple, if i have this string : "i_Id Mega (hex)", i want to encode this and get : "i_Id_x0020_Mega_x0020__x0028_hex"

I don't find a way to do this in powershell. All help is welcome !

Thanks, Tristan Sébillet

You apparently want to replace space characters with _x0020_, open brackets with _x0028_ and remove closing round brackets? What have you tried already and what failed? — Theo

This should do it:

$inStr       = "i_Id Mega (hex)"
$outStr      = ""
$uniChars    = " ("
$removeChars = ")"

foreach( $char in [char[]]$inStr ) {

    if( $uniChars.Contains( $char ) ) {
        $outStr += '_x' + "{0:x4}" -f [char]::ConvertToUtf32([string]$char ,0) + '_'
    }
    elseif( !$removeChars.Contains( $char ) ) {
        $outStr += $char 
    }
}

$outStr

Or use several regex -replace actions:

"i_Id Mega (hex)" -replace ' ', '_x0020_' -replace '\(', '_x0028_' -replace '\)'

Result:

i_Id_x0020_Mega_x0020__x0028_hex

That's what i want but i need to do it for all special characters. So the -replace solution is a bit long..
