Based on this StackOverflow answer, I wrote this PowerShell script:
$charId = [Int32][char]$args[0] [System.Reflection.Assembly]::LoadWithPartialName("PresentationCore") | Out-Null [System.Windows.Media.Fonts]::GetFontFamilies("C:\Windows\Fonts") | ForEach-Object { foreach ($face in $_.GetTypefaces()) { $glyph = $null $face.TryGetGlyphTypeface([ref]$glyph) | Out-Null if ($glyph -and $glyph.CharacterToGlyphMap.TryGetValue($charId, [ref]0)) { $_.Source.Split("#")[1] break } } } Save it as a file with a ps1 extension; I called it fonttest.ps1.
Before PowerShell will let you run scripts, you'll need to do Set-ExecutionPolicy Unrestricted -Scope CurrentUser. Then you can run it like so:
.\fonttest.ps1 你 The .\ is important, and you'll need to be in the same directory as where you saved the script. That last character is the one you want to test all fonts for. You'll get a printout of all font families that have a glyph for that character. On my computer, the above command produced this:
