问题
a while ago i were googling to find out how I could make a batch menu with a more "professional look" instead of using symbols such as:
|=====|
|-----|
|_____|
to make outlines around a menu in batch. but I had no luck. today i randomly found this article:
https://web.archive.org/web/20151204182221/https://http-server.carleton.ca/~dmcfet/menu.html
and it explains that by using ms-dos (edit.com) I can do this.
but as my computer is a 64 bit win 10. I dot have the edit.com so.... how could I make this kind of menu look by hand? (printing special characters shown on left side of the header "STEP 3, Lines, Lines, Lines.")

Here's a batch + PowerShell menu maker I've been working on. Set the values in the batch portion, and the PowerShell stuff will auto resize and reposition as needed. When a selection is made, the console buffer restores its former contents, effectively vanishing the menu.
It looks like this:
Here's the code. Save it with a .bat extension.
<# : Batch portion
@echo off & setlocal enabledelayedexpansion
set "menu[0]=Format C:"
set "menu[1]=Send spam to boss"
set "menu[2]=Truncate database *"
set "menu[3]=Randomize user password"
set "menu[4]=Download Dilbert"
set "menu[5]=Hack local AD"
set "default=0"
powershell -noprofile "iex (gc \"%~f0\" | out-string)"
echo You chose !menu[%ERRORLEVEL%]!.
goto :EOF
: end batch / begin PowerShell hybrid chimera #>
$menutitle = "=== MENU ==="
$menuprompt = "Use the arrow keys. Hit Enter to select."
$maxlen = $menuprompt.length + 6
$menu = gci env: | ?{ $_.Name -match "^menu\[\d+\]$" } | %{
$_.Value.trim()
$len = $_.Value.trim().Length + 6
if ($len -gt $maxlen) { $maxlen = $len }
}
[int]$selection = $env:default
$h = $Host.UI.RawUI.WindowSize.Height
$w = $Host.UI.RawUI.WindowSize.Width
$xpos = [math]::floor(($w - ($maxlen + 5)) / 2)
$ypos = [math]::floor(($h - ($menu.Length + 4)) / 3)
$offY = [console]::WindowTop;
$rect = New-Object Management.Automation.Host.Rectangle `
0,$offY,($w - 1),($offY+$ypos+$menu.length+4)
$buffer = $Host.UI.RawUI.GetBufferContents($rect)
function destroy {
$coords = New-Object Management.Automation.Host.Coordinates 0,$offY
$Host.UI.RawUI.SetBufferContents($coords,$buffer)
}
function getKey {
while (-not ((37..40 + 13 + 48..(47 + $menu.length)) -contains $x)) {
$x = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown').VirtualKeyCode
}
$x
}

FIX: in order to create a menu like this. you will need to use an editor such as notepad++ open a new notepad ++ file. then goto format and select western europe OEM-US charset.
then simply go here: https://en.wikipedia.org/wiki/Box-drawing_character
and copy paste the symbols you want for your menu in notepad++ and save.
example: Displayed in notepad++ :
echo ╔════════════════════════════╗
echo ║Bill register/database Menu ║
echo ╠════════════════════════════╣
echo ║ 1. -Register a bill ║
echo ║ 2. -Check Bill Info ║
echo ║ 3. Set payment ║
echo ╚════════════════════════════╝
displayed in normal notepad :
echo ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ»
echo ºBill register/database Menu º
echo ÌÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ͹
echo º 1. -Register a bill º
echo º 2. -Check Bill Info º
echo º 3. Set payment º
echo ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ
so as you can see. it works with normal notepad too. but its easier to work with it in notepad++ as it displays what it actually look like.

It's not necessary to worry about code pages or file encodings at all.
When you are on windows 10 you can use the Character Set - DEC Line Drawing Mode
This uses ansi-escape sequences to show borders.
The border characters are represented by the characters jklmnqtuvwx.
for /F "delims=#" %%E in ('"prompt #$E# & for %%E in (1) do rem"') do set "\e=%%E"
REM *** Enable DEC Line Drawing Mode
echo %\e%(0
echo lqqk
echo x x
echo x x
echo mqqnqqk
echo x x
echo mqqj
REM *** Enable ASCII Mode (Default)
echo %\e%(B
The output is
┌──┐
│ │
│ │
└──┼──┐
│ │
└──┘
