Originally created by @kghost on GitHub (Dec 23, 2017).

As Unicode TR11 suggested, all neutral characters map to halfwidth or narrow characters.

According to EastAsianWidth following characters are neutral:

✖ 0x2716
✚ 0x271A
✭ 0x272D
✹ 0x2739

so they should be halfwidth or narrow, but is rendered full-width in CMD.exe, which is causing terminal disarrangement.

Your Windows build number: (Type ver at a Windows Command Prompt)

Microsoft Windows [Version 10.0.16299.125]

This might be a duplicate of #2066.

This looks like it was fixed at some point in the past - unsure when precisely:

printf "foo\u2716bar\nfoo\u271abar\nfoo\u272dbar\nfoo\u2739bar\n"
