Are strings always null terminated?

[beleon]

Janet stores the length of strings, so they don't need to be null terminated. I found that at least some strings are null terminated, but is this guaranteed or just a coincidence?

EDIT: I had a bug in my test setup, my original answer (below) is not correct, janet strings are in fact always null terminated.

No. After some testing I found out that janet strings are not guaranteed to be null terminated.

JANET_STRINGs are always null-terminated, but they might contain null bytes inside their payload as well, so they aren't exactly C-string compatible. JANET_BUFFERs are not null-terminated.
