utf8_en/decode deprecation

[amazeika]

These two functions are deprecated on PHP 8.2 and going to be removed on PHP 9.

We need to replace these.

Solution

Encode

mb_convert_encoding($string, "UTF-8", mb_detect_encoding($string))

Decode

mb_convert_encoding($string, "ISO-8859-1", "UTF-8")

Implementation

Make use of https://github.com/joomlatools/joomlatools-framework/blob/master/code/libraries/joomlatools/library/legacy.php for re-defining the functions when removed.
