Set-Theme agnoster

Clone the powerline repository from GitHub.

git clone https://github.com/powerline/fonts.git

afterward, do the following:

cd fonts
.\install.ps1

Wait for all the fonts to be installed.

From inside Cmder / ConEmu settings dialog, ensure you choose the powerline font you wish to used. i.e. Menslo ... for Powerline, etc. Also make sure you set the same font for the Alternative font to use, otherwise some characters will not show.

1. Add the following function to your powerline $PROFILE. To edit your $PROFILE, just run ise $PROFILE from within PowerShell:

function U
{
    param
    (
        [int] $Code
    )
 
    if ((0 -le $Code) -and ($Code -le 0xFFFF))
    {
        return [char] $Code
    }
 
    if ((0x10000 -le $Code) -and ($Code -le 0x10FFFF))
    {
        return [char]::ConvertFromUtf32($Code)
    }
 
    throw "Invalid character code $Code"
}

stole from here.

2. Run the following script inside PowerShell:

Write-Host "$(U 0xE0B0) $(U 0x00B1) $(U 0xE0A0) $(U 0x27A6) $(U 0x2718) $(U 0x26A1) $(U 0x2699)"
