Spinner characters don't have glyphs in any of the default console fonts on Windows

• I have read through the manual page (man fzf)
• I have the latest version of fzf
• I have searched through the existing issues

Problem / Steps to reproduce

The braille glyphs are not present. The fallback spinner made of slashes would be fine.

fzf/src/terminal.go

Lines 405 to 408 in 7191ebb

	if unicode {
	return []string{`⠋`, `⠙`, `⠹`, `⠸`, `⠼`, `⠴`, `⠦`, `⠧`, `⠇`, `⠏`}
	}
	return []string{`-`, `\`, `|`, `/`, `-`, `\`, `|`, `/`}

The problem can also be seen in screenshot from #2329 (the first yellow replacement character).

I don't have a Windows PC, but I have a Windows Server 2016 VM running on AWS. And it looks like the spinner is properly rendered on its cmd.exe. What am I missing?

Please note that I'm not at all familiar with Windows platform, so I'm open to any suggestions.

test-braille.bat

@echo off
REM save as this in UTF-8
chcp 65001
echo "⠹"
pause

When you run the batch, displaying the braille glyph depends on the font your console is using. I have tried Consolas, Courier New, Lucida Console and Raster fonts; none of them displayed the character correctly. I have got one font that works "NSimSun", but that's not a standard font.

What's the font you are using in your instance of Windows Server?

It's set to 굴림체, a Korean font. I don't remember if I set this myself, or it was the system default.

That clarifies why it works for you. The default font for cmd is Consolas and that font does not include Braille characters, so I would disable them in fzf for windows altogether (regardless --unicode, --no--unicode switches).
