Yes, this works for me.
This resolved problems with around 15 documents out of 1500.

Would you consider to make this change in upcoming release?

I found simliar code in class-wpsolr-model-abstract.php:132 that might need this change (and perhaps many more places?).

Might add that I am using:
Using Apache Solr, Opensolr SW-SOLR-8-0
and PHP 8.0, WordPress 6.2

I had similar problem. I think the problem is a multibyte character that is truncated in field snippet_s. See the question-mark in snippet:
"snippet_s": ". {\n \"S.Arsene.pdf\":\" Y-a-t-il un int\u00e9r?"

This origins from content
"content": ". {\n \"S.Arsene.pdf\":\" Y-a-t-il un int\u00e9r\u00eat \u00e0 r\u00e9aliser

Fix for Version 23.0:

I suggest fixing the code here wpsolr-pro/wpsolr/core/classes/models/post/class-wpsolr-model-post.php:257 to replace substr with mb_substr.

Patch:
