ubuntu line wrap not completly working

[Hero9909]

Ubuntu 18.04
zsh 5.4.2 (x86_64-ubuntu-linux-gnu)

if i go back in my history the line is overwriting some chars, ive use the workaround to set LANG to en_US that fixed a missplaced cursor if i go back in wraped lines

locale:
locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
