@Mark-Bestwick The warning is obviously not triggered by spipu/html2pdf but from tecnickcom/tcpdf which is a dependency of this package.

Which version of tecnickcom/tcpdf are you currently using (composer show tecnickcom/tcpdf)?

Version 6.3 should fix the warnings.

You can also hack the files: . In simple_html_dom, find all the regex that contain “-“ and escape the character (“-“). Around lines 682 and 1363 . Find the arrays with indexes {1} and replace them by [1] (I remember 2 occurrences (I think in tcpdf main file) . In tcpdf/include/tcpdf_fonts line 1666, add a test that returns “” if $c is empty (static function unichr($c, $unicode=true) {if(empty($c) {return “”;}

you can also activate debugging and it will find the locations for you.

Sorry, simple_html_dom is not part of tcpdf. PS: I have checked TCPDF v6.3 and it does not solve the problems. >> hacking.
