mb_convert_encoding is deprecated in PHP 8.2

Hi @dbielke1986 Is this a bug in the Caxy library related with.

php-htmldiff/lib/Caxy/HtmlDiff/Table
/TableDiff.php

To Fix the issue you can add the following code
instead
line 592
$htmlDiff = HtmlDiff::create(
mb_convert_encoding($oldContent, 'UTF-8', 'HTML-ENTITIES'),
mb_convert_encoding($newContent, 'UTF-8', 'HTML-ENTITIES'),
$this->config
);
to
$htmlDiff = HtmlDiff::create(
htmlspecialchars_decode($oldContent, ENT_QUOTES | ENT_HTML5),
htmlspecialchars_decode($newContent, ENT_QUOTES | ENT_HTML5),
$this->config
);

instead
line 630---
$dom->loadHTML(mb_convert_encoding(
$this->purifyHtml(mb_convert_encoding($text, $this->config->getEncoding(), mb_detect_encoding($text))),
'HTML-ENTITIES',
$this->config->getEncoding()
));

to

$dom->loadHTML(mb_convert_encoding(
$this->purifyHtml(mb_convert_encoding($text, $this->config->getEncoding(), mb_detect_encoding($text))),
'HTML-ENTITIES',
$this->config->getEncoding()
));

I think we need an MR for this issue before it should be "Needs review".
Can you push your changes to an MR?

Hi @dbielke1986 i you please review if this work i will create the MR

The issue is with php-htmldiff. The library needs the patch, and then the dependency revision needs to increase.
