Comment 5 for bug 1377873

My short-term workaround to recover old backup files with umlauts after UnicodeDecodeError:

export LANG=en_US.utf8
export LANGUAGE=
export LC_CTYPE="en_US.utf8"
export LC_NUMERIC="en_US.utf8"
export LC_TIME="en_US.utf8"
export LC_COLLATE="en_US.utf8"
export LC_MONETARY="en_US.utf8"
export LC_MESSAGES="en_US.utf8"
export LC_PAPER=en_US.UTF-8
export LC_NAME="en_US.utf8"
export LC_ADDRESS="en_US.utf8"
export LC_TELEPHONE="en_US.utf8"
export LC_MEASUREMENT="en_US.utf8"
export LC_IDENTIFICATION="en_US.utf8"
export LC_ALL=

deja-dup --restore folderWithUmlauts
