4.0.1. to 4.0.2. upgrade problem caused by a mod, using ? in descriptions

[molieman]

Prior to upgrading from 4.0.1. to 4.0.2., I disabled all mods. After the upgrade I noticed some 404 errors when trying to go to several forums, this is what I discovered.

This is the forum I was trying to go to "Welcome to MyCockpit ? New here? Introduce Yourself!" and went to the following link, and got a 404 error:
>>>>>>.mycockpit.org/forumtest/forumdisplay.php?138-Welcome-to-MyCockpit-%AE-New-here-Introduce-Yourself

I looked at my live site (4.0.1.) and it is as follows >>>>>> .mycockpit.org/forumtest/forumdisplay.php?138-Welcome-to-MyCockpit-New-here-Introduce-Yourself (and this works at /forumtest/ the 4.0.2. upgraded site)

If you notice the upgrade put a "%AE-" in between "MyCockpit-" and "New-here" If I take out the %AE- out, it will go to the proper link.

I have several other forums that does the same thing, each has the ? in the description, and any new post I create with ? in it the description, will do the same with inserting %AE- (all modes are disabled).

Obviously, it has something to do with inserting ? in a description and changes it to %AE- in the link.

Support says this does not happen in a clean 4.0.2., I can understand that, I think. So it comes down to what mod is creating this change. But why is it happening when I have everything disabled.

I'm trying to prevent deleting all mods, I would hate to loose any data collected or just plain start over, lot's of work, you all know that.

Does the above problem look like a problem you've had, seen or heard of, and do you know what mod may of caused this?

Does deleting mods in admincp, delete all files related to that mod?

Extremely frustrated..... and LOL

Addition:
The test is running at: www.mycockpit.org/forumtest/
No live data lost
