Likewise the LI18NUX 2000 specification (p. 39) says
  "The msgid argument is a null-terminated string."

And likewise the LSB 3.0
https://refspecs.linuxfoundation.org/LSB_3.0.0/LSB-PDA/LSB-PDA/baselib-dgettext.html

And likewise the Solaris implementation's documentation says:
    "The msgid argument is a null-terminated string."
https://docs.oracle.com/cd/E88353_01/html/E37843/gettext-3c.html#REFMAN3Agettext-3c
