I see that 2 byte characters are currently supported:

https://en.wikipedia.org/wiki/UTF-8

that is, essentially everything up to U+07FF. Example:

Ç (U+00C7)
You can paste this or enter it with Alt + 128 on Windows, assuming Windows
Terminal is being used. However it seems 3 and 4 byte characters are not
supported. Example:

₧ (U+20A7)
with PowerShell, you can paste the character, or on Windows you can enter as
Alt + 158. However Yori does not accept paste or keyboard input of this
character.

Its not just that one character. Its many 3 byte characters, for example these
too:

⌂ U+2302
⌐ U+2310
░ U+2591
▒ U+2592
▓ U+2593

Regarding this original posted issue, it has been resolved. However two new
issues exist. First, if you enter echo ! and then HOME, you get this:

$ |echo !

where | is the cursor. However if you enter echo ∞ and then HOME, you get
this:

|$echo ∞

so the cursor moves behind the prompt, and the input is shifted one character
back. I think this is not correct behavior. Second, now that 3 bytes characters
have been resolved, I would point that 4 byte characters have issue. For example
if you try to enter 😀 (U+1F600), you get this:

$ echo ��

��

Let me know if you want me to create new issue for either of these items,
thank you!

On the Windows Terminal: NG. ∞ requires ONE CELL . This view seems to be same as you report.

Note that other shells are successful with Windows Terminal. For example
PowerShell:

and Nushell:

But, on the Windows Terminal, nyagos prints it as is.

If � is displayed, it is possible that your terminal has no fonts for the
character.

I get this result with Nyagos and Windows Terminal:

Compare with Nushell and Windows Terminal:

I am entering 😀 using (Window key + ;) or (Window key + .)

ok, everything looks good! Thank you!

Maybe I have a new shell now :)

Actually, I do notice one more issue. If I enter a composable character such as
https://emojipedia.org/man-farmer with Nushell everything is fine:

but if I enter the same character with Nyagos, only the output is correct:

@ zetamatta for my use, the ZWJ is not needed. But I wanted to raise the problem in case you wanted to address it. For my needs the issue is complete, thank you!

ZWJ is supported on 4.4.9_0.
