bugs remaining in 1.4.2 with php8.2

[mcbmcb0]

🐛 Bugreport

Hi I know 1.4.2 is now maintenance, but I’ve updated to it recently due to the comments re likelihood of 2.0 have 'paper cut' bugs. There are still a number of bugs in 1.4.2 on php 8.2. I’m listing some here that’s I’ve patched (hacked) as it may help someone else and possibly it may be relevant to 2.0. I get some of these as appear to have some emails with less common windows encodings. I’m not claiming these are elegant of efficient fixes, but work for me, for now. I’ve posted up a couple before in previous issues. I'm not suggestinganyone resolves these - just TBA for the next 1.4.2 user. Looking forward to a stable 2.x!
