macOS: utf box drawing characters are not used in boxes/tables

[0-issue]

For some reason utf box drawing characters are not being used on macOS with same conf as on Linux.

% locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL=

% echo $LANG
en_US.UTF-8

Possibly relevant part of conf file:

  ## document.codepage 
  #  Charset options.

    ## document.codepage.assume <codepage>
    #  Default document codepage. 'System' stands for a codepage determined by a
    #  selected locale.
    set document.codepage.assume = "System" # <- doesn't matter if changed to UTF-8 alongside, and/or force_assumed is set

    ## document.codepage.force_assumed [0|1]
    #  Ignore charset info sent by server.
    set document.codepage.force_assumed = 0
