utf8_encode is deprecated in PHP 8.2

PHP Deprecated: Function utf8_encode() is deprecated in .../vendor/szymach/c-pchart/constants.php on line 48

c-pchart/constants.php

Line 48 in 373786c

define("EURO_SYMBOL", utf8_encode("€"));

If I understand it correctly utf8_encode("€") is the same as "€" (see https://3v4l.org/dERVv), so I think the utf8_encode() can simply be removed.

I suppose it is a leftover from when this library files were encoded in ISO-8892 or some other standard. I suppose it would be fine to remove the deprecated function.

Looks like this can be closed, because merged and #19343 can be reviewed. Now PHP 8.2 is actual stable version (since a week)

Hello there, can you confirm it was released in v3.0.16 ?
Thanks!
