  • Your Windows build number: (Type ver at a Windows Command Prompt): Microsoft Windows [Version 10.0.18894.1000]

  • What you're doing and what's happening: (Copy & paste specific commands and their output, or include screen shots): Arrows in the arrow unicode block have different widths and sizes. Some take twice the width and some appear bigger than the others

    I checked with the command for ($i = 0x2190; $i -le 0x21F0; $i += 16) { for ($j = 0; $j -lt 16; $j++) { Write-Host -NoNewline $([char]($i + $j)); }; echo "" } and here's the output

    As you can see, some vertical arrows take 2 cells and some horizontal arrows lie in a single cell width. That breaks the table layout like this

    wttr in

  • What's wrong / what should be happening instead: They should have at least the same point size and width. I think all of them should be in a square (i.e. double width)

FWIW here's the above wttr.in output on Linux
