I have also used page.clean_contents(sanitize=True) after each insert_htmlbox, still it does not print this line properly

"अधिक जानकारी के लिए customerservice@axismf.com। निवेशकों को केवल पंजीकृत म्यूचुअल फंड से ही लेनदेन करना चाहिए, जिसका विवरण www.sebi.gov.in पर उपलब्ध है -"

Its because of the highlighted in bold character in the text string.

[smithah]

The pipe character if present in the html text to be inserted replaced it with - Alternatively, use one of the HTML entities for the pipe character, e.g. | (or the more meaningful |

Now its printing the characters correctly as given below. Is there any other way to handle special characters in the insert_htmlbox while printing text with special characters. Thanks

[smithah]

| or | using either of the two html entities instead of the pipe symbol solves the issue for now, finding the symbol in the text and doing a text replace with either of the above html entites solves the issue as of now.

I must confess that I am confused. Are you reporting an issue or not? In the end you seem to say that you found the correct way to achieve what you want.

In any case I see no problem caused by any of PyMuPDF or MuPDF. At best, this is a Discussions item therefore, I am going to transfer this.
