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.

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"
}
