PHP 8.2: mb_convert_encoding(): Handling HTML entities via mbstring is deprecated

[gharlan]

Using the mbstring "encoding" HTML-ENTITIES is deprecated since PHP 8.2: php/php-src#7177

mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead

It is used here:

parsedown-extra/ParsedownExtra.php

Line 628 in fd33d68

$elementMarkup = mb_convert_encoding($elementMarkup, 'HTML-ENTITIES', 'UTF-8');

This should be resolved by the changes #172, the HTML encoding has been completely rewritten. I'll leave this open until that is merged.

This issue is getting quite old now, and there doesn’t seem to be any movement on it. Have we give up all hope?

Meanwhile, I was able to replace the offending line with:

$elementMarkup = mb_encode_numericentity(htmlentities($elementMarkup, ENT_QUOTES, 'UTF-8' ), [0x80, 0x10FFFF, 0, ~0], 'UTF-8' );

This is more-or-less copied from one of the comments on php.net. I have no idea what’s going on here.

Here is another option that works for me:

$elementMarkup = htmlspecialchars_decode(iconv('UTF-8', 'ISO-8859-1', htmlentities($elementMarkup, ENT_COMPAT, 'UTF-8')), ENT_QUOTES);

Any chance on getting this resolved soon now that PHP 8.4 is out?
