PHP error

Hi @sirrahikkala

Actually is not that old, we are loading version 1.27 and the latest is 1.28, see here. It seems that you’re passing some illegal char to the PDF HTML, which is causing the error.

Alternatively you can change the converter tool with the code snippet below:

add_filter( 'wpo_wcpdf_convert_encoding_tool', function( $tool ) {
	return 'uconverter'; // default is 'mb_convert_encoding', alternatives are 'uconverter' (PHP8.2+) or 'iconv'
} );

If you never worked with filter hooks, please read this documentation page: How to use filters

Hope that helps!

To be fair “we” are not passing any illegal char by just using the plugin in woocommerce so it’s a bug somewhere else. Our product names do contain umaults and copyright/trademark symbols but those should be obviously handled correctly by plugins.

Are you able to show us a PDF sample with fake customer data somehow?

I could send actual files privately to some address but that error is reported in admin interface by Query Monitor.

Did you tried the code snippet as well?
