I'm on a laptop running Windows 10. I try pressing Alt+2713 to give a "✓" character, but instead I get a "Ö" character. Any thoughts as to why this might be?

  • Alt+251 gets a check mark...alt-codes.net

    @Moab Strictly speaking, that's a square root sign; U+2713 is a different character. (Also, in locales that aren't US English, the top 128 ASCII codes can be different. For me, Alt+251 produces ¹.)

  • You gotta type the plus sign too. Literall alt PLUS 2713 (on the numpad). You can do the ones with non 0-9 hex as well, but you gotta type the letters on the left side without letting go, and depending on what application in GOOD LUCK as it probably has something bound to at least one of those (e.g. alt-a through alt-f). edit: just saw the below answer. Yeah, you gotta enable the registry entry. This should be standard by today because the average person isn't going to know how, nor want to do that., but it's super usefull. I use +2047 for ⁇ which works in filenames, while a regular ? doesn't.

By default, the numeric keypad way of entering characters by code can only access the first 256 characters. (I believe these are defined by your system's code page for non-Unicode programs.) Codes bigger than 256 get wrapped around, so code 257 actually gets you character 1.

To enable the entry of all Unicode characters by code, create a string registry value in Computer\HKEY_CURRENT_USER\Control Panel\Input Method called EnableHexNumpad with the value of 1. Then you'll be able to enter any character by holding down the right Alt key, pressing the + button on the numeric keypad, entering the hex code (2, 7, 1, 3 in your case), and releasing the Alt key. You may need to log off and back on before this input type is enabled.

Note that the non-+ method of entering ASCII characters by code will continue to wrap around even after you enable this mode.

    How would I do this on Windows 11? I tried adding EnableHexNumpad but it did not work

Instead of trying to remember that ✓ is U+2713 (which I am unable to), I can suggest trying a piece of software I maintain called WinCompose. It inserts itself in the keyboard input chain and when using the default Right Alt as a compose key, lets you enter combinations such as:

  • Right Alt @ / for ✓
  • Right Alt @ X for ✗
  • Right Alt [ Space ] for ☐
  • Right Alt [ / ] for ☑
  • Right Alt [ x ] for ☒
  • … and thousands more

There is a GUI that lets you search for sequences and characters. Of course if you only know the Unicode codepoint for a given character and not the (supposedly intuitive) combination, you can still activate Unicode input in WinCompose and do the following:

  • Right Alt u 2 7 1 3 for ✓

Finally, note that Windows doesn’t let you enter Unicode characters beyond U+FFFF with the EnableHexNumpad key, so you won’t be able to enter e.g. U+1F4A9, but WinCompose lets you do this:

  • Right Alt u 1 f 4 a 9 for 💩

  • with EnableHexNumpad you can type characters outside the BMP by typing the surrogate pair

  • Slight addition, it's not self explanatory, or at least to me it wasn't, but you are not supposed to hold down the compose key (Right alt) but just press it, and then type the other keys.

After reading this I have discovered right-alt and left-alt produce different results for the same code.

To get GBP I used to enter left-alt 0163, which produces ú. I should be using right-alt 0163, which produces £.

Since I use my right hand on the keypad, pressing right-alt with the left hand is not as convenient as pressing left-alt.

Try using right-alt instead of left-alt.

The best I have come up is typig the numeric sequence slower. I want to type é, so I go Alt 130: é, but if I type as fast as I can, I get ♪, which is the so called "eighth note" music symbol, which is normally made with Alt 13. Bottom line, it seems to be a problem of keyboard sensitivity and those damn "help" anti-repeat features. Maybe the keyboard is dirty and the Alt key doesn't hold steady and drops after the 1 3 and doesn't get the 0. Anyway, the solution for now is pressure air clean the keyboard and tinker with the typing speed. Microsoft continues its relentless regression to the Middle Ages... ♪♪éééé♪♪♪éé

  • Interesting discovery on the speed. But if your assumption is wrong about the anti-repeat (which is adjustable), you will have maligned Microsoft unfairly (on this one issue). :-) In general, answers are better if you focus on the technical issue and avoid commentary.

  • I think this is kind of a separate topic. You might also want to check your keyboard's matrix technology. Traditional, low-cost implementations will jam keys, when others are pressed simultaneously, to prevent ghosting. If you are a typing speed champion, you might want to look out for keyboards with the so-called n-key rollover feature. For more info, see en.wikipedia.org/wiki/Key_rollover.
