Hi
I have found your article
PNG patch for reading zTXt chunks
I have a zTXtComment that I cannot read. Perhaps you can help me (It might be
french):

Here is a patch to add support for reading compressed text chunks
(zTXt) and storing them in the info dictionary. With this patch, both
compressed and uncompressed (tEXt) text chunks can be accessed uniformly.
I've come across some text tag discussions on this mailing list from
many years ago.
