The Windows key has no Unicode equivalent, so use ⊞ like Wikipedia and many others do
Posted by jpluimers on 2021/08/23
lFor Mac keyboard keys, almost all (except the old solid and open Apple logo’s) have a Unicode code point, see for instance the modifier keys from the [WayBack] List of Mac/Apple keyboard symbols · GitHub (the “Alt” column has a solid Apple logo in the bottom right; on non-Mac systems it will look differently as it is in the Unicode private range: [WayBack] Unicode Character ” (U+F8FF): ‘<Private Use, Last>’):
Sym Key Alt ⌃ Control ⌥ Option ⇧ Shift ⌘ Command
These are the code points for the “Sym” column:
- ⌃ – [WayBack] Unicode Character ‘UP ARROWHEAD’ (U+2303) (less wide than the below three)
- ⌥ – [WayBack] Unicode Character ‘OPTION KEY’ (U+2325)
- ⇧ – [WayBack] Unicode Character ‘UPWARDS WHITE ARROW’ (U+21E7)
- ⌘ – [WayBack] Unicode Character ‘PLACE OF INTEREST SIGN’ (U+2318)
Keys on many platforms
Based on the above, I found a way longer list, including keyboard pictures at [WayBack] Unicode Keyboard Symbols ⌘ ⏎ ⌫ covering keyboards from:
- Apple
- Windows
- Linux
- Sun Microsystems
- List Machine
Windows logo key has no Unicode equivalent
The only Unicode code point that comes close to the Windows logo key is [WayBack] Unicode Character ‘SQUARED PLUS’ (U+229E):
Unicode Data Name SQUARED PLUS Block Mathematical Operators Category Symbol, Math [Sm] Combine 0 BIDI Other Neutrals [ON] Mirror N Version Unicode 1.1.0 (June, 1993)
I found this out via [WayBack] Is there a unicode character for the Windows key? – Super User (thanks miroxlav):
For non-techies on Facebook, use workaround seen on Wikipedia: ⊞ Win.
Since you want to display the character on the Facebook where you have no control over fonts and there is no such character in Unicode at the moment, you can use mathematical operator Squared Plus (code point 229E) to imitate Windows logo as Wikipedia does in article on Windows key and in other keyboard-related articles.
Excerpt from the article:
- ⊞ Win opens the Start Menu
- ⊞ Win+D shows the desktop (hiding even non-minimizable windows), or restores hidden windows when pressed a second time.
- ⊞ Win+Tab ↹ cycles through taskbar buttons. This key combination is reassigned in Windows Vista.
This is for instance used by Wikipedia Windows key: Use with Microsoft Windows – Wikipedia: ⊞ Win
- …
- ⊞ Win+R opens the “Run Program Or File” Window.
