Display Unicode Emoji in PowerShell
Ok, that was easy: I have to use UTF32 instead of Unicode:
$CharBytes = 169, 244, 1, 0[System.Text.Encoding]::UTF32.GetString($CharBytes)
Another way to do this in one line is:
[char]::ConvertFromUtf32(0x1F4A9)Even better still:
"`u{1F4A9}"Edit:
Above, "`u{}" is a way to escape a unicode character to be interpreted by Powershell. This is built into Powershell itself.
Here's another way demonstrating the high and low surrogates, because the code point has over 16 bits. The result is actually a 2 character string. If you try to display each character individually, it will look like garbage.
$S = 0x1f600$S = $S - 0x10000$H = 0xD800 + ($S -shr 10)$L = 0xDC00 + ($S -band 0x3FF)$emoji = [char]$H + [char]$L$emoji😀Reference: http://www.russellcottrell.com/greek/utilities/SurrogatePairCalculator.htm
Or to get the code back:
($emoji[0] - 0xD800) * 0x400 + $emoji[1] - 0xDC00 + 0x10000 | % tostring x1f600
