I looked at the iconv use, and it looks like it should be pretty easy
to make iconv a configurable option -- whether that would be accepted
upstream is another question.

But, I finally realized that my problem was triggered by an upgrade to
openssh's "scp" utility v8.8 which uses the SFTP protocol by default
instead of the SCP protocl. [If I wanted to use SFTP, I would have
typed "sftp" not "scp".]  It turns out that with openssh 8.8 "scp -O"
works fine with dropbear. Unfortunately there's no config file or
environment variables for scp like there is for ssh.
