I had a document in office XP that had a "p" with a tilda ("~") under it, in 
subscript.
I opened the document in open office, and viewed it, and the "p" was there but 
the "~" had turned into a red "¿".

This is what the command string looked like, with the "¿" in it:
size 12{ {p}  cSub { size 8{ sim } } } {}

I modified it to:
size 12{ {p}  cSub { size 8{ "~" } } } {}

and it displayed perfectly, I wouldn't bother posting this, but I am a school 
student, and I am constantly using office 2k at school and then comming home 
and opening the same documents, so while there are bugs like this I cannot use 
open office, simply because of time issues.
There were a few more display errors, similar to this, but I am new to open 
office and "IssueZilla" (I think that's what it's called), so I figured I would 
just post about one first.
