Unless you are using 5.4.2 or 5.4.3 (can't recall which now, 5.4.3
I think), _NSUtilities.UTF8StringEncoding returns the incorrect
"UTF8" string, no hyphen. This can cause the request to think that
the encoding has changed ( ! "UTF8".equals("UTF-8")) and it then
discards the form values. But with the "multipart/form-data" it
then can't recreate them so you get null. My bug notes say, "The
hours this has cost me..."
Try using rr.setContentEncoding("UTF-8");
Is this an issue with WO 5.2 and 5.3 or just 5.4?
There are two issues. One, if the encoding gets changed and you are
using "multipart/form-data", the form values are lost. Two, UTF-8 is
more "proper" than UTF8 and in WO 5.4.x, WO has been moving toward
this as a standard.
Will changing usages of UTF8 to UTF-8 cause any issues with WO 5.2
or 5.3? I ask because we have been using
_NSUtilities.UTF8StringEncoding in a few places for years now and
have not come across this issue, maybe we've just been lucky. I
don't want to change anything unless I am certain that this will
definitely not break anything. Obviously we are going to test any
changes we make, I just wanted your opinion on this.
I don't think there is a practical difference, both seem to work for
the time being. UTF-8 is more correct. You just have to be certain
to be consistent and just use one of them.
