When compiling the attached source snippet I get:
g++ -c foo.cpp
foo.cpp: In instantiation of ‘void f< <template-parameter-1-1> >::operator()()
[with <template-parameter-1-1> = int]’:
foo.cpp:9:14: required from here
foo.cpp:4:33: error: char-array initialized from wide string
4 | constexpr unsigned char p[1]{};

With g++ --version
g++ (GCC) 8.1.1 20180712 (Red Hat 8.1.1-5)
this compiles without any errors.
