如何在php cli中键入unicode字符

Question

I work with php cli, so on the command line, on a Linux computer. I want to type in a unicode character. How do you do that?

Suppose the character is the euro sign.

In vim I do: ctrl-v shift-u 20ac Enter.

In bash I do: ctlr-shift-u 20ac Enter.

So how in the php cli?

Answer 1

You can do:

echo "\x20\xac";

To echo the raw bytes, but what gets displayed will depend on your terminal settings. Things get... complicated.
