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."
