Ok.  Whatever, I just updated my owncloud docker to nextcloud and its working fine so i'll just use that.  I was just reporting a bug but if no one wants to look into it that's fine.  Its not php as its the same version in both my dockers and its not owncloud as I have it running in another docker now fine.  THe only difference is the base distro and the iconv module showing up as unknown instead of 2.19 as it does in the other docker.
