Hello r/powershell,

I have two functions: New-BlockCharacter takes a character, and outputs a here string that represents this character:

Function New-BlockCharacter {

    [CmdletBinding()]

    PARAM(

        [char]$Character

    )

    Switch ($Character) {

        "A" {
@"
 ██████ 
 ██  ██ 
 ██████ 
 ██  ██ 
 ██  ██ 
"@
        }
        "B" {
@"
 █████  
 ██  ██ 
 █████  
 ██  ██ 
 █████  
"@
        }
        "C" {
@"
 ██████ 
 ██     
 ██     
 ██     
 ██████ 
"@
        }

    }

}       

An exmaple:

New-BlockCharacter -Character "a"
 ██████ 
 ██  ██ 
 ██████ 
 ██  ██ 
 ██  ██ 

The other function ConvertTo-BlockCharacter accepts a multi character string, calls New-BlockCharacter once for each character, and then "glues" the resulting here strings together. The result is a single multi line string that contains all block characters.

Function ConvertTo-BlockCharacter {

    [CmdletBinding()]

    PARAM (

        [String]$String="Test"

    )

    $Blockcharacters = foreach ($character in ($String.ToCharArray())) {

        New-BlockCharacter -Character $character

    }

    $sb = [System.Text.StringBuilder]::new()

    # iterate from first to last row of each character (is always 5)
    for ($i=0; $i -le 4; $i  ) {

        # iterate through each character
        foreach ($Blockcharacter in $Blockcharacters) {  

            # cut character in rows
            $BlockcharacterRows = $Blockcharacter -split "`n"

            # append current row of character to a new string
            [void]$sb.Append($($BlockcharacterRows[$i]))

        }

        # append new line to string
        [void]$sb.AppendLine()

        Write-Verbose ("`n$sb")

        # continue with next row

    }

    $sb.ToString()

}

An example:

ConvertTo-BlockCharacters -String ABC
 ██████  █████   ██████ 
 ██  ██  ██  ██  ██     
 ██████  █████   ██     
 ██  ██  ██  ██  ██     
 ██  ██  █████   ██████ 

It works fine, but only in ISE. If I run the same in the PS console, the output is rubbish:

ConvertTo-BlockCharacter -String abc
 ██████
 ██
 ██
 ██
 ██  ██  █████   ██████

I already tried to run it in the console of a different PC. I have no idea whats going on here. Can anybody help? Thank you
