Since #9935 documented multiple people getting bit by a Unicode-corrupting bug in
cx_Oracle 5.0, it might be a good idea to have the database notes section of the docs be a bit more clear on the fact that 5.0 should not be used (currently it says, misleadingly, "4.3.1 or later" in one place, while stating the requirement of 4.x further back in the paragraph.
The attached patch tries to make this clear, and also recommends
cx_Oracle 5.0.1 which, per upstream announce, resolved the bug.
If one of our Oracle gurus (I'm cc'ing Ian on this) could verify the text (and maybe double-check against 5.0.1 to make sure it really did fix things), I'll commit this and do a backport into the 1.0.x docs as well.
