How to use unicode characters in Windows command line?

Try:

chcp 65001

which will change the code page to UTF-8. Also, you need to use Lucida console fonts.

My background: I use Unicode input/output in a console for years (and do it a lot daily. Moreover, I develop support tools for exactly this task). There are very few problems, as far as you understand the following facts/limitations:

• CMD and “console” are unrelated factors. CMD.exe is a just one of programs which are ready to “work inside” a console (“console applications”).
• AFAIK, CMD has perfect support for Unicode; you can enter/output all Unicode chars when any codepage is active.
• Windows’ console has A LOT of support for Unicode — but it is not perfect (just “good enough”; see below).
• chcp 65001 is very dangerous. Unless a program was specially designed to work around defects in the Windows’ API (or uses a C runtime library which has these workarounds), it would not work reliably. Win8 fixes ½ of these problems with cp65001, but the rest is still applicable to Win10.
• I work in cp1252. As I already said: To input/output Unicode in a console, one does not need to set the codepage.

The details

• To read/write Unicode to a console, an application (or its C runtime library) should be smart enough to use not File-I/O API, but Console-I/O API. (For an example, see how Python does it.)
• Likewise, to read Unicode command-line arguments, an application (or its C runtime library) should be smart enough to use the corresponding API.
• Console font rendering supports only Unicode characters in BMP (in other words: below U+10000). Only simple text rendering is supported (so European — and some East Asian — languages should work fine — as far as one uses precomposed forms). [There is a minor fine print here for East Asian and for characters U+0000, U+0001, U+30FB.]

Practical considerations

• The defaults on Window are not very helpful. For best experience, one should tune up 3 pieces of configuration:

  • For output: a comprehensive console font. For best results, I recommend my builds. (The installation instructions are present there — and also listed in other answers on this page.)
  • For input: a capable keyboard layout. For best results, I recommend my layouts.
  • For input: allow HEX input of Unicode.

• One more gotcha with “Pasting” into a console application (very technical):

  • HEX input delivers a character on KeyUp of Alt; all the other ways to deliver a character happen on KeyDown; so many applications are not ready to see a character on KeyUp. (Only applicable to applications using Console-I/O API.)
  • Conclusion: many application would not react on HEX input events.
  • Moreover, what happens with a “Pasted” character depends on the current keyboard layout: if the character can be typed without using prefix keys (but with arbitrary complicated combination of modifiers, as in Ctrl-Alt-AltGr-Kana-Shift-Gray*) then it is delivered on an emulated keypress. This is what any application expects — so pasting anything which contains only such characters is fine.
  • However, the “other” characters are delivered by emulating HEX input.

  Conclusion: unless your keyboard layout supports input of A LOT of characters without prefix keys, some buggy applications may skip characters when you Paste via Console’s UI: Alt-Space E P. (This is why I recommend using my keyboard layouts!)

One should also keep in mind that the “alternative, ‘more capable’ consoles” for Windows are not consoles at all. They do not support Console-I/O APIs, so the programs which rely on these APIs to work would not function. (The programs which use only “File-I/O APIs to the console filehandles” would work fine, though.)

One example of such non-console is a part of MicroSoft’s Powershell. I do not use it; to experiment, press and release WinKey, then type powershell.

(On the other hand, there are programs such as ConEmu or ANSICON which try to do more: they “attempt” to intercept Console-I/O APIs to make “true console applications” work too. This definitely works for toy example programs; in real life, this may or may not solve your particular problems. Experiment.)

Summary

• set font, keyboard layout (and optionally, allow HEX input).

• use only programs which go through Console-I/O APIs, and accept Unicode command-line arguments. For example, any cygwin-compiled program should be fine. As I already said, CMD is fine too.

UPD: Initially, for a bug in cp65001, I was mixing up Kernel and CRTL layers (UPD²: and Windows user-mode API!). Also: Win8 fixes one half of this bug; I clarified the section about “better console” application, and added a reference to how Python does it.

I had same problem (I'm from the Czech Republic). I have an English installation of Windows, and I have to work with files on a shared drive. Paths to the files include Czech-specific characters.

The solution that works for me is:

In the batch file, change the charset page

My batch file:

chcp 1250
copy "O:\VEŘEJNÉ\ŽŽŽŽŽŽ\Ž.xls" c:\temp

The batch file has to be saved in CP 1250.

Note that the console will not show characters correctly, but it will understand them...
