Comment 31 for bug 1770929

For me this bug was actually triggered by another new bug in lftp caused by glibc upgate, see #1902832 which was obfuscated by this bug.

I found the patch from 19.04 disco which was mentioned in #19 which fixed the unicode error for be and revealed the other bug.

The change related to unicode is quite small, patch file "02-unicode":
